:bigsmile:
The whole kit was pretty sweet, and riding the bike for myself, itās quite fun. Iām thinking of a kit myself, but not from the rude and misinformed guy.
feilox, I canāt seem to open the site, it says: āThere has been an error processing your request

For a small compact bike like the Strida, I think friction drive is the only way to go. Dave, does the system cause a lot of tire wear if itās made like this:
When the motor is not driving the wheel, the silver wheel actually bounces up and down lightly, and I noticed that there wasnāt a lot of pressure on the wheel. Only when the motor is spinning, the cylinder would be tightly pressed against the wheel, with the help of the motor. (If you know what I mean, sorry canāt seem to describe it properly.) The more torque the motor was delivering to the wheel, the more tension the cylinder would exhibit on the tire.
When the motor is not engaged, the cylinder would bounce and spin along with the wheel with almost no friction. I actually think thatās pretty ingenious.
Is this a patented invention or are there some kits just like this? I only see gasoline power friction drives.
Thanks for the link, but the only reason why Iām not sure I can use a hub motor kit is because my wheels are 16 inch. I couldnāt find any of that size.
A thousand bucks for a cycling aid? Thatās like half the price of a good bike.
Spend the money on a gym membership and use your legs!
Best advice ever, thanks. 
what I would do is find an old 600 ninja and salvage the motor off it to use. that lil bike should go pretty good with it
That engine outputs almost 100kW! Probably will rip the frame apart. :bigsmile:
there are many sizes, 16, 700 etcā¦ You guys gotta research and find them. There are about 3 cheap American makers right now under 500. Really good cosidering they are charging 1,000 for a custom electic bike. Also check your local area for bike rules. In mine any bike that over X cc or goes over 30mph must be registered. that green website is down. But thereās another company with a similar name. I just canāt find the link. Itās probably the same manufacturer and parts.
Thanks for the tip. The regulation here is 30kph (18.64mph), but Iām not sure if Iām inclined to stick to that limit. 
Wow! Then I read this (sadface):
Yea my cousin learned the hard way. He got warning from a police officer when he was going down the trail at 30+ MPH. Heās a big guy around 300+ lbs. so not pedaling gave it away. Since he didnāt get a citation they made someone come and pick up the bike, lol. We still ride it around in the countryside though. He got another one but this time it goes only ~15MPH (24volt).
A friend of mine got a bike with a kit installed from this co: http://www.bionxinternational.com/bionx-international-north-america/. I think it's pricey, but he loves it - assist on hills, can set the %, etc. real nice UI on the console.
Do you know where i can buy āHidden Powerā friction kit or a simliar kit?
It certainly is for sale in Korea, but not sure where else.
LOL
i just picked this up in hongkong. itās the āGNGā mid drive kit so it uses your rear gearing for climbing ability!
Looking at the smooth aluminum drive wheel in the setup in post 22 I wonder about the drive under wet or muddy conditions. The old Velosolex friction drive used a textured grit covered wheel attached to a small 2 stroke engine which sat over the front wheel. The engine was pivoted and the weight of the engine pressed the grit covered wheel against the tire. No clutch so the engine was pivoted under rider control to engage and disengage the drive. To minimize tire wear the rider was supposed to pedal the bike to get it moving before engaging the running engine with the wheel. The engine was started by pedaling the bike and then engaging the drive with the wheel to turn over the engine.
A minimalist moped design but ubiquitous in France when I was there in 1972.
