yeha the controllers are in, ill post when there finished and ready.:thumb:

So far my 36V goldenmotor ebike is fun to ride but with the three 17.2Ah SLA batteries I have (got for free) I find I can only get about 6km of travel on them (without any pedal assist and some small hills) and 24km/h max. Is this normal or are my batteries near the end of their life?

My work is 5km away so it's not so bad, but I'm wondering what performance I might get out of a 36V/10Ah LiFePo4 pack. Any experience with similar battery pack and what numbers you get? (speed, distance travelled at full throttle, etc.?)

500w motor i assume? yes there probly is something up with your free batteries, i got 25k range at 32kph on 36v 10ah sla when they was new.......

Yes, 500W motor. Thanks for the info. :) I've been wondering what type of range I should be getting out of my batts.. started looking around for some new ones last week; no luck yet.

karma, at endless-sphere I found the following suggested conntection setup for Grubee motors. Let me know when your controllers are ready for sale and I will post my findings. Will you have ebrake (kill) switch connections?

hey karma, are you going to make any for lower voltage? before there was a range and now it's 48v.
I see you raised your price too :(

karma, here is a labelled pic of my hall connector. Just provide me with any further instructions that i will need. Let me know if any more pics or information is needed. thanks

I am curious how you now feel about your e-bike conversion using this particular kit and li batteries. I'm looking for a conversion kit and want to spend around $700 - right in your ball park.

I have about 10 miles to travel to work and wanted to take the bike a few times a week. The terrain is a combo of low hills and flat areas (no major hills). Your feedback is appreciated.

Hey karma, is this colour diagram you posted for the 48v/600w "ecrazyman" controller?

ok its ready to ship, if you get the chance post a pic of the throttle connector. just to be sure its the right colors.


Here is a pic of the throttle and controller throttle connector.

Including a 'direct fit' throttle will be alright. I haven't had the bike long enough to see if the fuel gauge is accurate; I thought the lights may also be useful for minimal troubleshooting.

Karma, is your site still "http://74.12.202.60:81/"? it never seems to be up

I'm looking for one of your modded golden motor controllers

thx jim....

After reasing through 9 pages and thinking i knew what i was after i realise i am TOTALLY confused..... but being a total noob i figure thats kind of allowed. But id really like some advice from someone.... ideally from karma as he seems to know a whole lot about this stuff :P but i can understand if hes busy :)

OKay, the way i see it there are 4 parts to the process, and i hope that this may hopefully turn into a definitive answer on the subject. I really tried to follow everythong but got so lost :(

First part, the hub motor. Front or rear?? Does it make that much difference?? Hopefully someone who has ridden both quite extensively can give us an answer on this one.

Then the actual motor. I was initially looking at the 36V golden motor, but some people have stated the rim is cheap and not well made, however some reviews have said the crystallite 5303 motor is very good. Can anyone confirm this? Even though i am an aussie and only allowed 200W, i am wanting a 500W motor.

Secondly, the batteries. As far as i can tell LiPO4 are the best. Okay great. I was hoping to get a 48V and use it on a 36V hub like Karma, but how will that change the range?? Obviously the controller is an issue here which will be mentioned later.
http://www.atenenergy.biz/Foxx%20Specs.htm i was looking at these ones, but its so overwhelming, whats the difference between the 10ah, 20ah etc.? How do you know which one to get?? I was under the impression that a removable battery is best becuase you can just slide it in and out and take it and charge it at work. However im not sure how these batteries would be charged..... one the battery front with 48v i was hoping to get a top speed of 40kph(about 32mph) and a range of atleast 40km.

Thirdly, is the controller. I can understand the difference between 36V and 48 V, but are they much of a muchness? Does the conroller control things like Regen braking and instant start vs. pedal first? Would you guys reccommendregen braking?? So as long asthe controller is rated for 48 v and 500w, is that all that matters? or am i missing something big?

Finally is the installation. Is it straight-forward to install, even for a complete noob like me? How about this business of modifying the controller as Karam mentioned to tweak it... how difficult is that?


From reading this thread these are the types of questions i would imagine someone interested in getting a e-bike would like some solid answer too( or atleast thats what i beleive) as there is a WHOLE heap of information on the net, but it can become confusing very quicky and confudlled to the pont it may put noobs off the idea.

Id love to hear peoples answers and responses and look forward to trying to build a cool, fun and free emmision bike.

I am in the same boat as you. After reading all nine pages and going onto this forum and others, I am a bit confused, but have the basics at least.

I have narrowed my selection down to a xlite or a we hub motor, but not sure which model yet. I am pretty much set on the LifePo4 batts, but not sure on the amp hours yet, but most likely will go for the 48v for the extra speed. The consensus I have gotten so far is to go as big as you can afford. So if you think 15ah is enough then you shoould actually go for 20ah. etc. etc.

I most likely will go with a front hub motor to balance things out in terms of weight distribution. The xlite models are a bit confusing, some refer to 4/5 series, some refer to x series, some refer to names such as Phoenix and Journey, and they all appear very similar in specs. This is why i might end up with WE kit instead.

The consensus I have gathered up so far is that regen braking is not really worth the effort.

I might end up also getting a Cycle Analyst as well, but that's only a nice thing to have, not a must have for my particular needs.

Ty,

Thanks for your reply...... Id love to keep conversing through this process. I initially thought it was quite simple but there are just so many choices.... and not much reviews...

I myself am set on those LifePo4 batteries..... and 48V ( i think that will be plenty) but not sure of the amphours.... what does that affect is it the torque or the top speed? or both?? And at what detriment to the range? I was thinking of 30 ah, just becuase i have seen some vids of ppl with that.... but dont want to range to only be 20 km :P

As for the front hub motor, i spoke to an importer today who imports both front and rear golden motors and he said he reccommend the rear. I enquired about the weight distribution and he said that was rubbish.... he believes the rear is better, due to the problems with a powerful motor and aluminium forks/front shocks (which can be potentially fixed with a torque arm).

He also stated that if you have rear suspension then the weight of the motor is couneterbalanced by the battery for a smooth ride.... dunno how accurate it seems kinda counter intuitive, especially from a physics P.O.V, but thats what he said. One point that hasnt been mentioned.... rear hub allows for easy disc brakes on front which are way more important than rear disc brakes.... so i personally think im going to go for rear hub. I am getting a change to ride a front hub in the next day or so so will get back to you.

yeah the xlite models are confusing and im finding it hard to find some solid info on them. Most websites have dead links and dead images..... really frustrating. I have read however that the 5304 model are very heavy... like 12 kg..... very poewful but very heavy...... depends if you are wanting a bike that you can zip around in or if your wanting something more like a mini motorbike. Me personally im just after something i can zip around in..... top speed of about 30mph ie 40 kph

If i want something the speed of a motorbike i would make an Electric Motorcycle rather than mountain bike
:-) But let me know what you decide and any thoughts...

Regen braking i agree with what your saying it takes away the coasting feature of all bikes, which i quite like and want to keep..... you can coast more than what the regen will provide.

Any ideas on the controller or battery brand?? I am wanting to try to make one as stylish as possibl and not look like a homemade botched job.

Please keep in mind that i dont own anything yet and am still researching like yourself b4 i take the plunge....

I too am in the same boat. I am new to E-bikes, but want one. I have a nice road bike (which is collecting dust) and also have a 'comfort bike' made by Trek (26" wheels) - which is one of a pair that my wife and I bought for fun exercise. They too are gathering dust. The Trek probably cost me $450 so I'd rather re-work it with a kit than to buy a complete new e-bike. I too have read all about Wilderness Energy, Golden Motors...etc and have checked out iZip bikes at a store in Dallas Texas (my home) - lead acid sealed cell (but the bike was quite cool for $900). I live 10 miles from work and can get there via a bike trail with low rolling hills - so the bike is a perfect alternative to driving. I think I want to get the best equipment wtih the most simple installation process - which appears to be a front wheel-based system with NIMH or LI type batteries. I'm pretty technical - but am comfortable with taking someone elses proven solution without re-inventing the wheel on what I need (that is a pun actually). So, I would be pleased to learn what selection you guys (?) go with to help me narrow the process.

Good to see that I am not the only ebikeless newbie here.

I am lucky to have several ebike shops here, including ebike.ca (renaisance bikes) and JVbikes GWEV, and several other prominent ones on the web. I pass by renaisance bikes every day to and from work, so one of these days I'll pop in.

I haven't really researched Goldenmotors that much, but I hear they are quite poplular. I don't know of any local suppliers here yet. We do have a local company called Rayben bikes, which nobody has mentioned yet. they are pretty close to where I work, too.

I did find out that there are different types of Lifepo4 batteries, so not all Lifepo4's are the same. apparently Pings are so far the most popular as he has the best track record on ebay.

I don't like the purpose built schwinns from Canadian tire. I've seen them in stores here and don't really like them at all. I want to convert my own bike.

as for amp hours, I believe that is distance mainly, but it does affect top speed because it has an effect on total wattage output of the battery and wether or not it can burst out 2C or 3C when your motor requires it. Voltage is mainly for top speed, but again, it affects the total wattage output of the batt as well. this is what I have gathered from other posts. I am by no means an expert here.

I went with a Crytalite 408 setup with SLA 12 AH batteries. My range of 16km (10 mi) up and down some large hills has yet to cut the controller out. One of these days I will get around to seeing exactly what the range is on level ground.
At first I was against using a front wheel motor, but because of the weight of the SLA batteries, it seems to work nicely. Batteries on rear rack, front wheel motor.
I wanted a e-bike to commute to work, and in May of this year, with all the back orders going on here with batteries and such, I just jumped right in.
At this level, I can wait for the better batteries to come down in price, and still be able to use an e-bike.
I converted an old sears 18 speed I had been using for years, and really like it.

I guess what I am trying to say, its like a computer, because they change so much, find something that will suit you, and because these kits are so adaptable, you can start with an economical route, use it, find what works for you or doesn't , then upgrade next year or so.

Good Luck!

i have another 48volt controller in. setup for the goldenmotor if intersted.

karmabike@yahoo.com

Hey karma, I need that asap! I'm gonna email you right now.

sorry or its karmabike@yahoo.ca

sorry or its karmabike@yahoo.ca

yeah, my email bounced back

sweet!

On the hub motor does it say Crystalyte or Aotema?

crystalyte motors are NOT sealed because of wire out the side of motor, Falconev motors ARE sealed

Was the name on the hub motor Aotema?
Is the one you have still working? How many miles?

as for amp hours, I believe that is distance mainly,

I think this may be how long the battery can put out 12 amps
Any battery can put out 100+amps even the 1.5 volt EverReady. Just not very long
Short one out and watch the wire turn red. kink the wire then hammer it thin on the kink
