I'm going to try one!

Ahah it would be ironic if electric wheelchair need pedal in order to comply the law :D:p But one option would be to have the pedal at the hand level, and that wouldn't look too gimmick and allow 15mph on the road as e-trike

Hello, I'm looking for a smalish dc-dc converter for maybe 30-50W output on 48v-12v. The chinese ones are too big and bulky. Anyone knows where I can find one at decent price? Thanks

I want one!! Is it road legal?

I bought few motors (Q100H and BPM) and lacing motor is really a hassle. But would be good to see someone getting one.

Interestingly, a bigger 3kg mxus are available for folding bikes: http://www.aliexpress.com/store/product/36V-48V-250W-High-Speed-Brushless-Gear-Hub-Mini-Motor-E-bike-Mini-Motor-Front-Wheel/738588_1888888450.html 85mm dropout width only

Currently i have a cheap dawe 26" bike because I'm planning to park it outside overnight :(

I don't mind if it overspin lol. But I'm just worried the 36V doesn't spin fast enough or doesn't have enough power

I currently have 2 spare 36v battery. I was wondering if there I can buy this 36v one and have the same result? http://www.aliexpress.com/item/36v-500w-8fun-bafang-motor-BBS02-crank-Motor-eletric-bicycles-trike-ebike-kits/1957204198.html

Ok, I contacted them and they only want to deal with re-seller. Also, they mention there 4.1kg motor can go up to 32km/h max speed only. So it's not really a good picture I have about the company. I'll get motor elsewhere. Probably BBS02

OK thanks, I'm checking with bmsbattery then

Ok I'm almost there, here's the calculator: I'm thinking to get these BMX spokes with 1X pattern at 184mm: http://www.ebay.co.uk/itm/36-Halo-BMX-Spokes-Black-or-Silver-Stainless-with-Nipples-/111215652834?pt=UK_sportsleisure_cycling_bikeparts_SR&var=&hash=item19e4f82fe2 Everything's good and...

they are also selling crank motors similar to the bbs02 http://szxfmotor.en.alibaba.com/product/1953879444-0/Middle_drive_motor_with_geared.html

Agree with Amigafan. And we both have "superbike". Just having a decent non electric bike cost around £600. Maybe £350 for a cheap second hand? I can't see how you expect to achieve your target

ok thanks for the correction. 4.75mm off-set to the center of the hub is to cater for the freewheel? And it should be the same number for any bike? Or shall I place the motor to the bike and measure distance to bike center before ordering spokes?

so about 525 erd? and other data from the bpm should be correct too? I need to get some spokes now
