    Imagine how many people would be in alternative transportation if large biking cities like santa cruz could start a rebate program like that? the world would be a much better place, cuz face it.....its going downhill every single day with global warming and pollution. When we are sitting here 100s of years later dying more and more of cancer because the ozono-sphere thinning has wasted away any chance of blockage/survival from solar wind....they will wish their fore-fathers had ridden more electric bikes and regular bikes to stop the harmful effects.....okay so that seems far-fetched (well...honestly its not. soo extremely true that it is very frightening)...but we all get the idea.

    The FS is a little heavier than I expected, implies it's steel framed.

    Thanks

    Yeah, the LA Free Sport is rather heavy. The LA Free Lite, on the other hand, weighs only 48 lbs.

    I can't imagine that, over the long term, regular cocaine usage would raise your performance. After a while, I'm guessing, your health would go to pieces.

    Just wanted to put my opinion on the electric bikes. I really do not like them and I do ride a lot. I am a bike officer and I ride almost 30 - 35 miles a 8 hour shift. The added weight really sucks and when you are doing aggressive riding the added weight is also a pain. I have lost the back end quite a few times and dumped the bike in hard cornering quite a few times.

    My personal opinion is that they are great for communting on dry roads but take them off road or in the wet and watchout. Plus they only got for for an hour tops before the battery dies... at least on my model.
    Just your average club rider... :)

    Just out of curiosity, what would you do if 2-3 roadies ran a light and blew by you at 30+ mph in a paceline? A lot of cops I see around here are on cheap fuji mountain bikes with knobbies.

    I'm wondering if it's possible to pedal at a comfortable rate to keep the battery charged with an altenator powered off the chain ring. I'm thinking of a deep cycle, golf cart type battery. This would make it a true hybrid and close to a perpetual motion machine.

    Regenerative braking is possible, adds some weight to the system.
    EPS and the older ZAP DX models had regenerative braking, as did a handful of others.

    However, like any other perpetual motion machine, remember the laws of conservation of energy.

    The prices I've seen on police bikes aren't cheap, particularly Fuji.

    If they're roadies, I'd suggest they're on pavement and might be vulnerable to his two-way.

    This is state of the art power assist for recumbents. Lightweight lithium ion polymer batteries, range of 35 to 50 miles. I have it. I love it.

    Yeah, the idea is to get people off cars and into other forms of alternative transportation. Having an electric bike would be a better option than having a car. I had no idea you could actually RIDE the electric bike as a regular bike, as well as chug around the city using the motor. It would help for people with disabilities, or older folks, or just people who are not as into cycling. I bet with more electric bikes that have the option to actually pedal, we'd see more people using the option to pedal, and a new cyclist is born!

    Do they make electric recumbents yet?

Do you think as more electric bikes come out, that more people will purchase them to commute? Some of the bikes listed there will go 25+ mph for 10+ miles, or 15mph for 20 miles, the more you pedel, the faster you go, and the longer the range.

    As for cost, they range from $750 - $3000. Cost per recharge? get this, only five cents! No liscensing costs, registration, and insurance requirements!

    What are your thoughts? I think that in the next few years we will see more and more of these electric bikes on the road.
    The ranges listed in the sales copy is not very important. One can not give a range of miles for an electric bike. The numbers used are under ideal conditions. Unlike a person. the motor puts out a given wattage for a given time. If there is a hill, any wind at all, any extra weight, or you do a lot of stop and start (which uses a great deal of power, accelerating). or go at top speed the range will be less.

    You will eventually run out of power some day. Then you have a heavy slow bike. If the distance is too far you can not charge up fully at work. If you have a distance much shorter than the advertised ranges for a total of a day, and can recharge over night, then you are OK. The tire drive motors destroy tires quickly. For the money spent you can buy a pretty nice efficient road bike and have a lot more utility.

    Electric bikes have been around for a long time. They don't sell very well. The more expensive ones can go the distance, but if you do run out of power, you can't quickly add a can of electricity in a few minutes. Some of the high end ones
    don't have pedals and are HEAVY! Get a Litespeed!

    Ever notice how many electric bikes are being unloaded on ebay? Eventually the batteries have to be replaced too.

    I was recently at the Toronto International Bike show and I went to the BIONX booth. They have a wheel, brake, battery combo that costs about $1000 CDN. You can set it to anywhere between 25%-200% power assist. Braking on the rear recharges the battery with a magnetic braking system, and if you crank on the rear brake, the mechanical brake kicks in. There is also a system where you can recharge by pedaling the bike normally. Their system weighs 7.6 kg (as far as I can tell).

    I didn't get a chance to ride it - but it looked real cool. If anyone has any experience with them please tell me. More info at http://www.bionx.ca.

    I have a crystalyte X5 brushless dc hub motor on my rear MTB wheel. I have 2 36V Li packs (one on either side of the rear bike rack). I had to solder the 2 chargers essentially together through a switch which toggles between series and parallel. The controller is a 72V 20amp immediate start. So basically, in series, when everything is working right I can get up to between 30 and 33mph on flats. Even a small downslope can get me to 37mph or so. Today, all of a sudden, I lost most of the power when in series. It looks like the charger is not charging up one of the packs, or something went "bang" inside on of the chargers. I'm just discouraged about the poor reliability of the "home-made" system. Anyone have any suggestions on systems that will give reasonably fast speeds?

    Welcome, praskal!

    Do you know about the Yahoo Power Assist group? Many of the members know everything there is to know about electric bikes and battery systems. The address is: http://groups.yahoo.com/group/power-assist/. Check it out!

    I'm definitely not a do-it-yourselfer when it comes to this stuff. I was going to get a WE kit for my Trek hybrid and decided to get a Lashout instead, mainly because it's a turnkey electric bike. But you'll get lots of good advice at the Yahoo group. Good luck!

    I think one day I might get myself a kit I saw advertised on the net, I guess it was something like largoscooters.com.
    It has kits as low as 250 dollars. The main attraction is that it uses a hub motor, put in front (so it's a front wheeldrive). The rest of our bike will remain the same, gearing, pedalling, braking....
    One minor drawback might only be the extra weight of the hub motor and batteries.

    Hello folks,
    My first post here.
    I bought a Giant Lite this year as my daily transportation. I love this machine, it's a fantastic bike. I've had a few issues with it, but I brought a few of those on myself. It weighs a bit. Naked it weighs in the mid 40's and with all the crap I've added to this thing (dynamo, fenders, new fork, fat Brooks, panniers, kitchen sink, etc.) it's in the upper 50's now. Motor on, I'm as springy as a 19 year old on a track bike. Motor off, acceleration is glacial and hills are arduous.
    My daily commute is 16 miles, and I'm putting anywhere from 80-130 on it a week. The cheater switch has 3 settings on it: off, on, and economy (which delivers about 75% power). Riding with the switch in full cheat mode I'm getting a bit more than 24 miles on a charge {rolling hill terrain**. Using econ cheating and I get around 35 miles. And I've made it to my sister's and back (64 miles) by only economy cheating the hills. The battery has yet to show any aging, a 7 pound NiMH.
    My issue with it is the geared hub (originally a 5 speed, I think SRAM). It did not have a gear range that I could live with. If I wasn't using her for a daily commuter, I'd have no problems with it. With a dead battery in a driving rain, I of course live at the top of the big hill, I realized that I needed more granny gears. I swapped it out with the SRAM 7 speed, but it's not quite up to my requirements. I've cracked it in half (the drum break spun the retaining nut off, and outer housing of the hub separated). This week I decided to pony up and get a Rolhoff.
    All in all I love this bike. I can load her down with 100 pounds of groceries, and I can make the 12 miles home long before the ice cream has melted. When I show up at work in the morning I'm not covered in sweat. Well that's not true, I live in the south, not sweating outside is a good reason to check your pulse, but I'm not especially sweaty.
    With that said, it's not a moped. You have to pedal. And if you want to out pedal the motor (there is a speed sensor on the chain, at a certain point the motor cuts out, saving the battery on down hills) you'll find yourself working hard. It's a heavy hauling, work horse, bicycle, that happens to have a cheater motor. I've yet to have anyone ride it, not get off grinning, and passing spandex clad yuppie's kids on race machines, when you have a 50 lbs. bag of dog food strapped across the rear rack, just warms the heart.

    That sounds neat, AllenG. How much did you pay for it?

    What kind of rear carrier did you put on it to carry all that stuff?

    Can you post a pick of what it looks like now after you made it into a commuter?

    Thanks Mike,
    I shelled out just over a grand for the bike. I can't get a pic of it at the moment, it's in the shop due to the faulty drum brake. I'm returning the SRAM and having the Rohloff laced up right now.
    I put this Tubus rack on it, and a set of these Ortlieb panniers. When I get dog food I buy a case of cans (they come in a large flat cardboard box) and a big bag of dry food. I lay the bag on top of the cans and wrap them together with some saran wrap (a trick I learned at the hardware store). The plastic wrap holds the bag to the box of cans quite well and stiffens the whole thing up. I lay the whole bundle across the rack bungie the hell out of it, and it holds up fairly well.
    I'll post a pic of it fully laden as soon as I get her back. In the mean time she basically looks like example a,here (mine is also a 20 inch frame), with example b's paint job.

    The electric bikes I have seen in China are a bit snappier than the electric bikes we are seeing in the USA. I don't know how well they function. I have heard from the Chinese that their batteries aren't up to snuff.

    Anyway, they look more like a motor scooter than a bicycle, though.

    They have a very tidy box that sits on the rear carrier so you can put stuff in.

    About a year or two ago I posted a pic on bikeforums.net. I don't remember the post, but I included a couple of pics of the electric bikes and the rear carrier boxes. I thought about importing the rear carrier boxes so folks could attach them to the rear carrier on their bicycles.

    With the average one-way commute to work being less than 7 miles the electric bike is definately an option. I got the chance to ride one years ago and damn the thing was fast, smooth and quiet. I've seen 3 people commuting by the rather goofy electic scooter in the last 3 weeks. Never saw that before.

    first let me say hello from the uk
    just bought 2 electric bikes 4 weeks ago for the good lady and myself and ive got to say they do just what they claim sold the two mtbs, in 3 years they have covered about 20miles,at 56 years old i just couldnt come to terms with the hard work pedaling and the pain in my right knee evan after 1/2 mile riding.
    now i cant keep of the bike they are sakura cruisers with old style lead acid batterys range in pedal ass is 20mile heavy yes but must roll easy because they are easy to push in pedastrian only areas.
    upto know the longest ride ive taken is 13mile no knee problem and only took 2 hours to recharge out of the quoted 4 hour max so 20mile is probaly realistic.
    we have a round trip to work and back of 8 miles in the vw camper it took 13min on the bikes using cycle tracks most of the way it takes 17min and takes just over 1 hour to recharge.
    bought a trailer to do the weekly shop at asda (wall mart) it may be cheating in some peoples eyes but its the only way i would get back on a bike and enjoy it
