    You guys are so lucky! Here in bureaucracy ridden Germany it’s not as simple as a “200W limit”.

    Effectively anything that has a throttle is regarded as some sort of motorbike and requires insurance coverage + a licence plate. Some constellations even require a driver’s license.

    The only ‘free’ e-bikes are named ‘ped-elec’ and they may only give assistance (up to 25km/h). As soon as you stop pedalling the motor cuts out. Of course that requires sophisticated torque sensors somewhere in the crank-hub –> not cheap.

    Hah. I have a 1000 watt hub motor on my recumbent trike (tadpole style with two wheels up front). I power it off of 15AH 56V of Nanotech Lipo. Very stealth too. Top speed is about 45mph. Range is about 100 miles if assisting (which I do, because I need exercise).

    I liked it so much that I put the same hub motor on my mountain bike. But then I got a Yamaha WR250R dual sport motorcycle <- ever so much more fun!

    It’s pretty hot here at the moment, about 32°C and not a single cloud in the sky and no wind. I saw a guy in 100% black clothing going uphil on a bike – effortlessly. I was crawling along and suffering… That guy was practically spherical and shouldn’t have been able to do that. He apparently has enough dough to inflate his swollen paunch AND get an e-bike to calm his conscience. I was envious…

    I have a similar LED spotlight, if you want to save a few grams i am pretty sure it has a built in regulator. Great little spotlight.

    Love the Bike!!!!

    Great work on that electric bicycles. These students sure know how to build an electric bicycle for cheap. When I wanted to make my own DIY ebike I used an ebook from UltimateEbikeEbook.com and it was awesome – showed me everything I needed to know!
