those kits are 250W only

the folding is quick, about 5 seconds to fold if you are strong but can be a faff due to its size and weight. Apparently, the Zephyr-B is targeted at city commuters, who need a fast and powerful bike but have to take their bikes into lifts and trains. I rode it (the same bike that RobF had...

yes, email andy

this one (£579) is within your budget and also has bigger battery: http://wooshbikes.co.uk/?gale

Tonaro Enduro I wouldn't want to take any of them up 3 flights of stairs every night.

stop capitalizing the first letter of each word, my eyes are about to explode too.

some LED panels have light switch function. The fifth wire will be for the lights.

it's similar to the Viking E-Go: http://www.ebay.co.uk/itm/Viking-E-Go-6-Speed-Electric-Bike-Bicycle-Black-20-Alloy-Silver-Fully-Assembled-/131173849265

A few weeks.

This is the voltage graph of the three phase wires of your motor: The frequency of the alternating voltage at your three phase wires is around 20kHz to 30KHz when your bike run at 15mph. Think of the capacitor as a lift, going up and down carrying people. Its usefulness is measured by the...

anyone can tell you that maximum output power is not battery voltage * controller Amps and the BPM is capable of a lot more than 8km/h.

The motor is 8-Fun BPM I think you have a good idea but the program logic is not very logical. You can't build a virtual bike from components that people input to the screen alone, the result won't match reality unless you have intime knowledge of what each component is caapable of and how it...

I inputted the components of a woosh Big Bear, here's the result: speed: 7.5km distance: 217km capacity: 540WH power: 720W consumption: 2WH/km completely screwy. I gave up.

ha ha - very funny! not as well engineered as yours though. Live long and prosper!

you have something up your sleeves, haven't you? do you know the buyer?

there are two reasons for that: one, bmsbattery is the bellwether - their 09 sinewave controller, display, PAS, brake levers and cable harness kit is of similar specs sells for $85. Wholesale trade price for the kit is about $75. Add to that kit a BPM motor wheel and 13AH 40 cell battery - you...

ebay is full of cheap kits, £400-£500 are the norm, not the place to sell a £630 kit. I reckon it won't go at that price.

I am very interested in your experiment. The cap in the controller that is used to stabilize the average 36V Lithium ion battery is only 0.47F. If you go with 350F Maxwell D cells, the array will be equivalent to 350/18 = 18.4F, 41 times the capacitance of the one in the controller. Please come...

Jimmy, I take it that you watched this video: The guy on this video replaced the car battery with the lipo, like d8veh suggested. His supercaps did not help much. His supercap array consists of 6 x 350F Maxwell D cells connected in series. You'd need 3 of those arrays. You will get 15...

GXP BB90 is too wide for BBS02
