buying from China differs from buying from an EU country on one particular point: you can't send back something to China. This is because the Chinese administration have a very complicated procedure for importation such that most Chinese vendors would rather send you a new part than accept...

step through all rounder: woosh Big Bear LS.

If Morphix follows your solutions a) only supplying to retailers - retailers need branding support, those who resell/badge unknown brands run a huge risk of getting a dodgy batch and can't return it, b) only supplying to the public at what would be the true market cost - that's better but would...

The BPM motors need a controller with a minimum rating of 17A but more typically, 20A. In theory, your controller can be very small, emits virtually no heat, presents virtually no danger so could be integrated inside the same housing as the battery pack. In practice, controllers need to be...

@ Kinninvie: Morphix's model relies on volunteers to keep cost down. I don't think it's an economically feasible strategy because as soon as the organisation sells something to a non-member, it needs to have an approriate infrastructure to provide a level of service commensurate with other...

What do you call cheap? under £500? there are plenty with 36V 10AH Litthium battery. Nobody makes bikes as heavy like the old Sakura or Powabykes any more. Prices are going down, quality is going up, so half dead bikes are much rarer than five years ago.

I can't see how the 'not for profit' model work in the real economy. Profit drives up quality of service. Without profit, you cannot guarantee a minimum level of service to your customers. For example, what if you decide to move on to another job? If the business model is not sufficiently...

how can you trust a piece of steel 1.5mm thick with a hole 28mm wide not to rock when violently pushed from one side?

cwah, you've got to take that fork off. It does not only look totally wrong on the bike but also looks dangerous. Just think that the front brake is only as good as how the headset is fitted. If the bottom crown race moves, the whole of the headset will slacken, the bearing will pop its balls...

the woosh Krieger does not have a rear wheel drive but a crank drive. Besides that, it should fit your height, weight and distance very well. It has a 20A motor, the previous woosh CD bikes have 14A motor, same range, about 50-60 miles and better weight distribution.

I test rode an EBCO UCL30 fitted with front wheel TranzX motor a couple of months ago. It's about as quiet and powerful as an front wheel 8-Fun SWX, which does not say much to the OP but for an idea, the motor noise never attracts attention because the chain noise when you pedal is usually...

what is the model of the LCD? if you have the BPM kit, then the LCD comes from KT electronics, the manual is here: http://wooshbikes.co.uk/2014/cstkit/lcd-manual.pdf The PO registers are listed on page 3. you select 36V for PO5 . If you have the Big Bear bike, the LCD comes from King Meter...

the £900 Woosh Zephyr-B has 30 mile range, the size to suit 6fters, the power to pull 15st and is well equipped for fast and comfortable commuting. You won't find a 10AH in-frame battery, a 20A controller, a 52T chain ring and hydraulic brakes on any other folder, certainly not at this price.

you can perhaps use a cheapo arduino shield to connect your PC to the I2C instead of using the O2Micro kit to interface the OZ890.

I don't have the KU63 circuit diagram but if the upper resistor of the divider is the 20k and the throttle is 30k, the initial supply voltage to the throttle is 3V. Plug the 10k resistor into the wires changes the value of the upper resistor to 6.6k = 1/(1/10k + 1/20k), the new supply...

a good commuting bike in London needs to have a few extra considerations beside the obvious fast depreciation of commuting bikes in general. Factors like: - how safe is the area where you are going to park your bike? simple things like saddle, lights, wheels and even QR skewer, if they are...

you should also pay attention to the suspension. Commuting is diiffferent from leisure cycling. Your back and wrists may get painful with long hours sitting on the saddle.

the throttle is easy to unplug and to remove, if I remember correctly, with a 2.5mm allen key. The mechanical spring load throttle moves a magnet. put a bit of grease around the moving part should do it.

stop worrying. All e-bike batteries are nowadays made with Lithium ion cells, their fire risk is minimal. The risk is highest when the cells are overcharged, they then release oxygen and swell. These batteries also have self extinguishing PVC packaging and incombustible shell, should a cell...

I'd look at the Woosh Zephyr-B. It's got rear 8-Fun BPM motor, front and rear hydraulic brakes, Kevlar tyres, will do 30 miles in all weather and it folds, that means you can take it in trains even in rush hours. It's also lightweight and stealthy.
