    Red face Pegasus electric bike conversion kit thingie

    How do you electric bike savvy good people feel about the following electric bike kit
    http://www.pegasuspowersystems.com/id102.html ?

    I can't find any reviews and I'm in a rush to get a motor for my bicycle and this one is tempting me over the BL-36 Wilderness model.

    Side note: If you know of a better kit under $400 shipped to Eugene, Oregon, I'll give you an internet cookie if you tell me about it.

    Thanks for your time :D

    I can't offer you much wisdom. But I do think Pegasus battery case, controller mount, rack look like something I would like. The fact that they make headlights powered from the propulsion battery is also a BIG plus.
    I would certainly give them a look if I didn't already have an ebike.

    Thanks for tipping us off to look there. Please let us know the results if you choose Pegasus.

    I hate to be the bearer of bad news, but I'd be more inclined to just get the motor and controller here http://www.electricrider.com/ as the first upgrade most people usually make after getting a kit is to replace the marginal lead acid (which usually doesn't last long, total life wise) battery pack, with a better NiMiH pack, and that necessitates a compatible charger too, so almost right away that's half the cost of your kit.

    A nice top of the line battery can be found here...

    Course, I know it gets pricey quick.

    well,
    price tells everthing.
    my battery 36V10Ah alone cost me more.
    my TF made-in USA cost 4000 dollars, but it is trouble -free for 13,500 km.
    the best ebike kit E+ /Google it/ is over 2500dollars.
    I don`t know why would people expect reliable mean of transport for less than 10 tanks of gasoline.
    Pay at very minimum one year worth of gasoline - 12 times $70 is....
    Do you want reliable or have your hands dirty every day with crap from China.

    I don't count that as bad news as it's stuff I want to hear. I was hoping I would eventually pick up a second battery for the bike. The Pegasus dealer place sells empty battery cases and judging by the dimensions of lead acid and NiMH listed at the link you posted I think I could fit the cells into the plastic case thing. But if the setup is **** I'll never need a second battery pack!

    Good point.

    Thanks for all the input. I'm presently waiting to hear back from someone I found who bought one on eBay.

    I tracked down someone who bought one of these through ebay feedback and they had good things to say about it so I bought one and just installed it and it's awesome. I'm not a technical person in this field so I don't know what all to say about it as a review.

    It took about three hours to install and it came with all the tools needed to install it. It is a lot more powerful than I expected, and it's faster than I want to go at full throttle. The battery case is 25 pounds but it pops on and off with the turn of a key which is great so I can remove it quickly to lift my bike onto public transit bike racks.

    The brake levers kill the motor when you put any pressure on them. The wheel was true. Everything mounted up just fine. The light and horn are nice. It zooms right along.

    If you ride your bike up and down stairs, on railroad ties, or heavy off road stuff, in my opinion the rack/battery mount is not strong enough. It's a bit wobbly when you jerk it around.

    There are two key positions for "on" and one for "off" and I don't know what the difference between the two "on" positions is. Any ideas?

    There are two gauges on top of the light and I'm going to guess one is for battery level but I have no idea what the other is. Any ideas?

    It shipped UPS and the box weighed 61 pounds. It took 6 days to get here.

    I had twist shifters but rarely used them so I'm not worried about them being slightly harder to use. The new brake levers are long enough that there is no extra reaching of fingers to grab the brake levers.

    It is rain proof, by the way. The seller, the manufacturer and the manual it came with all say it will work in the rain and I could definitely see where they sealed parts to make them rain proof.

    I'm very happy with it and I'm glad I won't have to eat so much anymore! People complain about the gas prices, but eating extra calories every day to fuel my bike adds up. I'm happy to answer any questions if I know the answers to them, or take extra pictures.

    BTW, are there any ebike kits that are *not* from China? As someone that has spent many a day and night defending and securing computer systems from attacks that originated in that country, I'd like to make my personal purchasing dollars stand by my beliefs, aside from the quality issues. Unfortunately, I'm not aware of any ebike components made in the US or Canada. So, I'm currently looking at the ez kits, which from the way people talk have good customer support, and are quality products as far as these things go.

    Hello,

    I was wondering if how your experience has been after a year with the bike? I have been burned twice trying to get a working ebike, and I am hoping the third time would be a charm. Found your posting, when I was trying to see what people think of the pegasus kits. Thanks for starting the thread. I greatly appreciate if you can post any update/insight. For example, have you been able to use it in colder/hotter weather? Is the battery still going? Do you have to charge it continouslly and once/twice a day? Does it handle up hills well? etc.

    Best,

    A.

    You've been burned twice? I've had good experiences so far with my 2 ebikes. Nothing has broken so far. I'm careful with my bikes, though. I have a Forsen hub motor and a Crystalyte 5303 motor. Both run great.

    Well, I guess I can easily be called an 'unlucky' one!?! :-(

    It seems as I need something with a 500W motor that has enough tourque. I am hoping to be able to go around 20-25 miles per hour (so you don't get killed driving in the traffic), and it would be great if it could cover about twice that in distance, if necessary. I also realize that the range probably will diminish as the battery starting to die out. I still haven't figured out what kind of battery I need, as everyone says something different. With motors, there is also seems to be a large number out there. I also have considered whether to buy an already built ebike, but in any case I hope my third attempt is a 'home run' rather than a 'strike out'! :-)

    The kits I have been looking at are:

    Electric Bull or Green Hornet from Falconev

    http://www.falconev.com/E-Bikes.html

    Crystalyte 5304 or 408 from

    http://www.electric-bikes.com/better...rystalyte.html

    and the one I was asking about Pegasus Power 680

    http://www.pegasuspowersystems.com/id102.html

    It looks from reading lots of posting that the one everyone is very happy with is the Crystalyte one. I have emailed Pegasus to see if I can find out more about their motors. Two things that make it rather attractive are price - less than $500 including shipping, and the rather water proof set up they have. I do want to be able to drive it to public places, and be able to lock it up without worrying too much whether it would be there when I get back (have couple bikes stolen on me), or whether the rain would be a serious issue.

    The first two option also leave me to find a decent battery, which does not cost an arm or leg. I was thinking of buying a ping battery, which doesn't seem to be cheap; but again is receiving good reviews from people.

    Your post mentioned that you have a Forsen hub and an x5303. Would you mind telling me how/where you got them, and what kind of battery you are using? Have you managed to 'water -proof' it? Any other suggestion/comment would also be greatly appreciated.


    Cheers.

    I bought my Forsen hub from cycle9.com but I don't think they carry them anymore. It's a very good hub motor but not good for hills. It's made for speed. It's German made and seems to be a great motor. I put about 300 miles on it before I switched to my crystalyte 5303. The only reason I switched was because I wanted more torque and speed and well, the 5303 got so many great reviews. The crystalyte motors are very good but they aren't good in the rain. I never ride in the rain, though. The nine continent motors are good in the rain. If you want to go with a crystalyte and ride in the rain, there is a chemical called ACF-50 that you can put inside the motor that will prevent it from rusting. It might not rust but someone has had their crystalyte rust before but he kept his in a garage so I wonder how it would do inside a house that's dry and air conditioned. I keep mine in my house. The crystalyte motors will take more punishment than the nine continent but it's still very close on durability. The nine continent can handle quite a bit.

    I got my 5303 from http://ebikes.ca . A 5303 with a 35 amp controller for $750. It's very well built. I've went off sidewalk curbs numerous times and even hit a very big pothole and never bent the rim or broke a spoke. No damage at all. I think they use a pretty heavy and thick rim...probably double walled but I'm no expert so I can't tell the difference but it's a very thick rim.

    If you want torque, the Ezee motor is pretty good. Also good with hills. Max speed at 48v is 24 mph. Max speed is probably around 20 mph at 36v. Ebikes.ca has a good reputation.

    I think you would do well with these brands of motors/controllers

    ezee
    nine continent
    crystalyte

    Ampedbikes.com uses a nine continent motor in their kits and I think e-bikekit.com also uses nine continent.

    I recommend going through http://ebikes.ca if you want to buy the last ebike kit because they honor their warranties and if you have problems, they have a great reputation for fixing the problem very quickly. They also sell ebikes that actually work and have been well tested and they toss the stuff that doesn't work so you know that if you buy from them, it's going to be a good product.

    As far as traffic goes, I was going 32 mph on a 30 mph road and I still had cars passing me.

    True! On the way home (about 7KM/5M), I am biking mostly uphill which is sometime very steep. When you are taking that kind of path, and dropping speed can be even deadlier! :-)

    Thanks for all the suggestions. I checked ebikes.ca. They seem to now only sell nine continent and Ezee motors now, although many of their info still is based on crystalyte! They have great prices on 2806 and 2807 models. Are these 400W-500W motors? Do you think is worth it to upgrade their 25A controller to a 40A one?
    Their batteries also seems to be out of my range. I also cannot figure out how much Ah I need! Would 36V/48V, 8Ah run this motor for a decent range? Would I better off trying to buy a cheaper battery from ebay, etc? I know the danger with it, but I have read good things about ping batteries, and they seem to be cheaper (there are of course much cheaper LiFePO4 out there, but I guess you get what you pay for!)

    I think you should go with a 25 amp controller because that allows you to buy almost any battery you want so you'll be able to shop around for a good battery rather than be limited to only High C rate discharge batteries (which are more expensive). You can still go wtih a 40 amp controller I guess but then you have to find a 2C battery that actually works well with a 40 amp discharge rate. And some of them that say 2C are not really 2C batteries. I have Thundersky that I use with my 35 amp controller and it just barely can handle it. I'd go with the 2806 Nine continent. Do they still sell the 2805 nine continent? That one really is built for speed. The 2806 is kind of mix between speed and hill climbing. I wouldn't go with the 2807. Either the 2806 or 2805 Nine continent. Or a crystalyte hub motor.

    Ok, if you go with a 25 amp controller, for a battery, it depends on what you want. Do you mind how big the battery is? Do you want something really small? Those are questions you need to answer. I would not buy a battery off of ebay.

    For batteries, if you go with 25 amp controller, you can get any of these:

    pingbattery ...from pingbattery.com
    Thundersky from elitepowersolutions.com (that's where I got mine...but they are a bit big but they are still good lithium batteries)
    lithium batteries from hightekbikes.com
    lithium and NIMH from ebikes.ca
    cycle9.com has some lithium but usually more expensive
    itselectric.ca has some but usually more expensive


    If you want a small battery then Thundersky are probably not what you want. They are smaller and lighter than SLA because it's lifepo4 but they are prismatic cells and they are very user friendly but they are kind of bulky but are very safe. They have a vent at the top to prevent fires. They are probably the safest lithium battery on the market. You probably want to go with lifepo4 since it's pretty safe. Careful because there is a difference between LIPO or lithium polymer and LIFEPO4. I hear that LIPO has gotten safer though but lifepo4 is still safer than LIPO. LIPO gives higher C rate, though.

    Pingbattery used to be a lot better. Some of his newer batteries have had some problems. Not sure why. The Thundersky's are better batteries in my opinion. People seem to be having a lot of trouble with the ping BMS's.

    The thing is that a lot of those ebay batteries are factory rejects I think. I don't have proof but how are they providing these batteries for so cheap. I think pingbattery.com might be also using factory rejects but he probably is better on the inspection but lately, I think he's been letting some bad ones through.

    Following your suggestion, I will order the 2806 Nine Continent. It comes with plug-in Cycle Analyst, which I was planning to buy anyway. As you mentioned, they also have a 2 year warranty, and their shipping to me (or back to them) is really cheap (I am in Canada). I am also taking you advise of sticking with the 25A controller - I just want it to work and not get into a race!! :-)

    The last decision I have to make is the battery. I am sticking with 36V, but have not decided to aim for 20Ah or 30Ah. Checked all the sites you had mentioned and more. Ping prices are the most reasonable for the buck (for LiFePO4); but your last post doesn't give them the highest marks. I actually considering using SLA batteries. They are heavier, have a shorter life span and discharge rate; but I can pick them from local stores here; and they are relatively inexpensive. I also came across a rather interesting solution:

    http://www.youtube.com/watch?v=zKKvP9wWrlY&feature=fvw

    Someone had used 36 volt Dewalt battery packs, which he claimed give him 20Ah. They are relatively cheap (Amazon selling them for $170 each). They are Li, and come with 1-2 year warranty. If it works, they are also very light.

    I also currently have a 36V, 12Ah LiFePO4 battery (only used for a month). Not sure if it is the problem with the battery or the controller (even might be the motor itself); but after couple of weeks of working fine, it does cut out on me. I will try out with the NC 2806 kit to see if it is working. Talking to at least 3 different stores yesterday, including ebike.ca people, it seems as you can use almost any size Ah battery. It just may last shorter (or longer). Also, if your controller draws too much, and you have a low C battery; I guess the battery BMS will cut out the power. (I wonder if that is the case with my current 20Ah Cylte controller?)

    Just one final, quick reply:

    I just ordered the NC 2806 with their new LiMn 48V, 8Ah from ebike.ca. As you had also mentioned, they recommended that I stick to 25A controller with this battery. Bought a light kit with it, and cannot wait until it gets here. Hopefully my third try would be the charm!!?! :-)

    Thanks again for taking the time, and answering all the questions and making great suggestions.

    Cheers.

    The Dewalt batteries are actually A123 cells which are the best on the market for lithium. They aren't cheap at all by any means. They are actually the most expensive batteries you can buy. Lithium is measured by the Watt-hour or WH. Those dewalt 36v packs are 36v 2.5AH packs so you get about 36 x 2.5 = 90 wh which will give you about 3 or 4 miles range before it cuts out. So if you bought two of them, and you say they are about $150, that's $300 for about 6 - 8 mile range. That's horrible. If you can find new dewalt packs on ebay for $50, that'd be a pretty good buy. Whenever you look at lithium, measure how many watt-hours it has in the battery and that will tell you whether it's a good buy. My 36v20AH thundersky was $360 + $30 shipping so $390. I got 36 x 20 = 720 wh so 390/720 = about 55 cents per watt - hour.

    I don't recommend SLA unless you think you just want to enjoy the e-bike for the summer and then it's not too bad. I think you should keep looking for a couple more weeks until your motor comes. Get a 2nd opinion on the pingbatteries. I personally don't think they are all that great but you are welcome to ask around and see what people think. Try endless-sphere.com forum . Someone just posted a ping problem today actually.

    about your current battery, yeah maybe that's what was happening. Hold off on buying a new battery because this new motor and controller might work fine with that battery. (nevermind, I just read your last post.)....yeah you can't go wrong with http://ebikes.ca ...I'm sure they'll hook you up with some good stuff. They got me a really nice motor and rim and controller. Been using it for a year now with no problems.

    When looking at lithium, you want to keep in mind what it's C rating is and how many continous amps you'll be using. Your new controller is a 25 amp controller . So for example, if you bought a Thundersky battery which is rated at 2C and it's capacity is 20AH...then 20AH x 2C = 40 amps. So you can use any controller 40 amps or under and it won't hurt the battery. So you take the capacity x the C rating = .

    So with your 25 amp controller, if you got a 10AH pack then you'd need one rated for about 2C or more. So a 15AH pack that's rated at 2C might be what is best for you as far as lifepo4 goes. Or just about any LIPO pack would work since those are all high C rate packs.

    I don't recommend SLA unless you think you just want to enjoy the e-bike for the summer and then it's not too bad. I think you should keep looking for a couple more weeks until your motor comes. Get a 2nd opinion on the pingbatteries. I personally don't think they are all that great but you are welcome to ask around and see what people think. Try endless-sphere.com forum . Someone just posted a ping problem today actually.

    Thanks for the link. Similar, but not exactly the same problem as mine. For one thing, mine was only tested with one controller (the first one never worked). Mine worked for about a week or so. I peddle and only have a short distance each way to and from work (total of 10 miles). The way back in mostly uphill, so it really pushes the 250W motor, so I made sure to help it as much as I could. Then, similar to what was described in that post, I lost the power half way there. Turned the controller off and switched off the battery. It came back after a few minutes, but died again not long after. As I repeated this, it took longer and longer to come back on, and eventually I had to wait at least several hours to get it back. Last night, following a suggestion, I tried to drain it completely at home with no load, and with a gentle throttle to draw small amount of current. Died the same way. Left on over night, and in the morning wasn't coming back on as before. Waited until the afternoon - charged it back, it had gone from just over 43V to just under 40V. It came back on, but the same as before.

    If there is any chance that I can use it; I will keep it. I can always use it when I want a longer range. Not sure if you can put them on series, being two different batteries, and different voltages; but if it is possible then it would be great.

    I am selling it dirt cheap to someone on Thursday - he seems to know more about batteries and power. Is there any way I can check it (without opening up the package) to see if I should hold on to it?

Been using it for a year now with no problems.

    My fingers are crossed! :-)

    When looking at lithium, you want to keep in mind what it's C rating is and how many continous amps you'll be using. Your new controller is a 25 amp controller . So for example, if you bought a Thundersky battery which is rated at 2C and it's capacity is 20AH...then 20AH x 2C = 40 amps. So you can use any controller 40 amps or under and it won't hurt the battery. So you take the capacity x the C rating = .

    I look at Thundersky, and you were absolutely right - For the money was an excellent buy. Having said that and being very new at this, I thought the safest route is to simplify!? It seems as you need to do a bit more work, that is you have to either watch the balancer manually (which is probably better any way), or make it work with BMS.

    The prices were also great at HighTekBikes, but almost all their batteries out of stock!

    So with your 25 amp controller, if you got a 10AH pack then you'd need one rated for about 2C or more. So a 15AH pack that's rated at 2C might be what is best for you as far as lifepo4 goes. Or just about any LIPO pack would work since those are all high C rate packs.
    I assume that if the battery has high C rate, and high AH, then the controller will just choke it off. Am I right?

    I bought a 30 amp 24 volt ping battery in the spring of 2009. So far no problems and it seems to be as strong as ever.

    I've never repaired a battery before but I don't think there is anything you can do that doesn't involve opening it up. It's probably the BMS that is causing the problem. If you wanted to check the battery, you'd have to open it up and take a volt meter and measure all the cells. The cells should all be above 2.5v if it's a lifepo4. And above 3.0v (I think) if it's LIPO. Your new battery should be fine if it was checked out by ebikes.ca and he said it would work.

    If you had a 250 w bike before, you'll love this one that you are getting with a 48v battery. It'll probably go about 28 mph.

    I just looked at the battery that you said you got. Is this it? If so, that's awesome. Super convenient. You could just remove that and take it in places with you if you want because it looks pretty small.
