Hi Jerry Simon kindly sent me a controller with a pedal sensor connection. I want to use it with a Tongxin fitted to a Brompton. I attach photo of the controller and wiring. The pedal sensor connection is the black connector with 4 wires, Black, Red, Green and White. Does any one have any...

Many thanks Jerry If you do have a controller with pedelec disk and sensor I would be interested. The Tongxin is sensorless. I already have cut outs on the brakes. Regards Ian

Hi I have a Brompton with Tongxin hub/controller and throttle control. A family member has difficulty with the throttle due to hand tremor. I would like to change the electrics so that it is pure pedelec without the need for a throttle. Is there any way I can do this with the existing Tongxin...

Thanks Ian

Hi I am looking for a wheel builder to lace a Tongxin into a Brompton size rim. Any suggestions? I have had one built by a well known firm and was disappointed with the rim run out. Catsnapper was mentioned by I cannot contact him as his PM box is full. Regards Ian

Many thanks for the replies. Jerry, reading your linked thread you show a very neat shut off switch. Can you give me the supplier name please. Regards Ian

No dealer. Home converted tandem and Brompton. Looking for any available switches with the intention of modifying existing levers to whatever switches I can source easily. Regards Ian

Hi Does any one know a UK source of the small micro switches with integrated cables as fitted to electric bike brake levers? Regards Ian

Hi Frank Many thanks, that is just what I needed to know. I really appreciate your help. Do you refer to the wheels by RPM so when you order from Bafang you order SWXU 250RPM? Are the Tongxin motors also all the same ratio with different windings for different RPM? Regards Ian

Hi Frank I was trying to establish if there are different models of the Bafang SWXU for different wheel sizes. They list 20 to 28 inch wheels on their web site. Is that the same motor for all sizes or are their different gears or windings for different size wheels? We are looking for maximum...

Hi I am looking to buy a Bafang hub motor. I see others are interested in these as well. Has any one a link to any technical data with detailed specifications that is available on the web. Regards Ian

Thanks. I have decided to go with the Bafang SWXU. I am not clear on one thing. Are there different versions of the SWXU with either different windings or different gear ratios? I am after hill climbing ability rather than speed as it is for a rider with pedalling difficulties. The motor...

Thanks for the replies. I like the free wheel ability on the Tongxin. Tried the original Tony Castles conversion at ATOB and was really impressed. The Electric Wheel Co price is outside my range. Does the Bafang run as freely as the Tongxin and will it fit Brompton forks? Regards Ian

Hi Can any one help me with information on the Tongxin motors to suit a Brompton and a Pashley tricycle. Is there a list any where of the different RPM motors available. Am I correct that the different speed motors are the same motor with a different ratio drive. I need possibly a lower...

Hi Following advice on the Forum I purchased a Cyclone kit from Taiwan. This is for a tandem. I need to extend the Throttle wiring. Does anybody recognise the connectors? Incidentally buying direct from Cyclone was interesting. I paid with PayPal. I received no acknowledgement from...

Hi I have decided that I am going to fit a geared chain drive kit so I get to use the existing bike gears. I have tried a hub motor bike and a Panasonic drive bike on the long steep hill outside our front door and they both fall short of what I am after. I have narrowed my search down to...

Thanks I will give him a try Regards Ian

Hi AtoB recently had an article about repairing a dead Lafree by using a sensorless controller. The supplier mentioned (Brett White) seems to have stopped trading. Does any one know of any other supplier of sensorless controllers? The control Brett was offering was a "Sankinda" and presumably...

Hi I am interested. Any way of getting it to Lyme Regis? Regards Ian

Hi I am a recent convert to electric bikes. I am so impressed that I want to add power to our tandem in the hope we can use it again. We have some specific requirements. We live in a hilly area with a 16% hill right outside our door. I assume this would mean geared drive and lower speed...
