Hi I would like to …
Hi I would like to offer to build a Web site describing how you do this. It seems like there are a lot of people who are interested, and I think it looks great but is very complicated. I would also like to start commuting to work on my new bike. Would you be willing to work on that?

Think of it as an exercise machine with variable resistance. Your workout depends on how much you use the throttle. You get a of a workout if you don’t use the throttle, but at least you can pick when to sweat and when not to sweat. Get your workout going home instead of having to change clothes and shower at work. If you are not feeling like a workout, don’t have one, but you can still bike to work.

I like your reasoning for putting the motor in the back wheel. Replacing one of those would be very expensive. Good tip.

Hi, I’m thinking about building a hybrid bicycle myself. I’m trying to choose which batteries to use. How many kilometers can you ride per pair of batteries and in what conditions? Also, what is your top speed and how long does it take to get up to that top speed?

And so what is that …
And so what is that yellow trailer he’s got on the back of the bike in the first part of the video, but not the last part? Surely it’s not holding extra batteries or anything…
I hate to be skeptical, but there is a long tradition of exaggeration surrounding electric vehicles of every sort.

Trailer was empty. The weak link in all electric vehicles has been the battery. These batteries charge in under an hour and have been going strong for about two years now.

mm doesnt that defeat the purpose of cycling?
for the exercise and no polution(considering if you electricity is not produce via hydro,wind, or solar)
however this is a good idea in the sense that bikes can no ascend the steepest of hills, thus making bikes more practical for a go anywhere for even the laziest of people….
keep riding mate….you’re doing a good job

Now I am almost mad I bought the front wheel kit, but I will try to be careful. I know I will be upgrading the batteries once I get greedy for speed. Also can you build me a battery such as the one you described 72 volts!! wow..

Thanks for the video. I’m sure you are man enough to not listen to the posters who criticize your bike and claim they can beat you. They are children in mind.
“The law will also come down on hybrid bike riders if guys run around at high speed. It would ruin if for everybody”
This is true. For anyone building one, just keep it on the low down when the cops are around and stay safe around “people powered” bikes.
Cool…

Efficiency on a regenerative braking system of this size is very poor with existing technology.
Your secondary question seems to be asked out of spite and probably does not deserve an answer.

when you go down hill does it recharge your battery? Also do you feel like you are better than people that have cars?

lol I have no spite but that was funny.
Why would it be inefficient? You would need a chip and some diodes. Detect when you press the brakes or press it enough to initiate recharge. A voltage regulator would be needed in order to raise the voltage over the battery spec voltage in order to push the current through to charge the battery. It’s been done for RC cars, real cars, trains etc why not a simple system for a bike? Just Do it.

It’s better to put the motor on the front for a good weight balance with the batteries on the rear but now you put all the weight at the same place and also you own weight is on the rear of the bike and after that you said you scare to bend you wheel on the front lol!!

Great video! I am now using a dewalt battery on my electric mountain bike thanks to your insight.
To all the critics… Have you tried riding one of these bikes? Its addicting.

Wonderfull can I have more in formation as to how you put the battery pack togather. and was their a controler in volved?

After riding around Seattle… I’m scared about my front wheel too. It’s hard to believe they actually spend money on fixing the road given the road surface quality in most areas.

That looks like …
That looks like Dexter Ave, heading N to S from Fremont bridge. Typically I’m pushing 15 mph up on my lightweight road bike, and about 45 mph down the other side of the hill – but I’m fit, strong, young and uninjured. The electric bike you demonstrate would be great for someone who needs some assistance and motivation to get back on 2 wheels. Great work!
I do wish batteries would become cheaper though – these would truly be the way of the future if they were.

Is this a homemade kit? What is the website to buy this?

Not a scooter. Must always pedal. Energy stored is about same as other batteries per unit volume, so range is the same also, which depends on how fast you go and how much you pedal. They weigh less and will charge fast if you buy a charger for each battery. You will not get 20 miles without pedaling with four of these. I always pedal and can milk twenty out of a charge but usually about 15 because I tend to cruise at about 22 mph.

i am impressed. looking forward to building the next generation for my rig. you are pointing the direction. the dewalt solution appears to be a simpler and less expensive alternative to lithium ion costliness. 20 miles with no assist? i get twelve with 36V. one trickle charger for four hours to recharge. do you pull out each unit every ride and then plug into individual chargers? i guess so. a bit of a hassle but a terrific solution. tell me more. i want more from my unit.

Not everyone should try to build one of these. Things break and you are on your own. If you are not electrically and mechanically inclined don’t attempt it. It also isn’t cheap. More info at hybridpowerbike website.
