So Wisper have had your bike since April last year and are not responding to you? Have you tried calling them using the number from their website 01732 762 393? Wisper have a good reputation with folks on this forum as far as I know, so am surprised they are ignoring you

Sounds promising, sending back just the controller or the whole motor? Hope the supplier comes good. Please name check them here if you end up getting good service so others can consider them for future purchases

Should be covered by warranty, only 8 mths old? Let us know how you get on with the warranty return https://bafang-e.com/en/oem-area/service/warranty-policy/

Although not ideal failing after only 800 miles, the price of a new controller at 75 quid is not a huge amount in the grand scheme of things. Imagine having the similar issue with an out of warranty bosch motor for example, and facing the possibility of having to buy a whole replacement motor...

The biggest thing you can do is ride is with the assumption that every car driver has the potential to not see you. Make eye contact with the driver, for example at junctions, if you can. Second guess their moves in where they are looking, if they are looking in the opposite direction, get ready...

Greetings from South Dorset. Really muddy 2nd shakedown of my newly bafang mid drive conversion 26" MTB yesterday. Mixture of frozen icy mud and pools, and really thick gloopey mud. Got so thick at times, the chain was slipping in the higher gears there was that much mud on the drive train...

It's pretty straightforward, here a video guide You can get the BBS01b in either 250w or 350w 36v, I paid about £270 for the motor kit and about £180 for the 17.5ah battery (Samsung cells), both from Aliexpress sellers

I've converted my 26" MTB with a Bafang BBS01b mid drive. Good fun off road with 85Nm. I'm using the stock 44t chainwheel and a 11-40 9 speed Sunrace cassette, pretty much goes up most hills in top assist mode

The battery looks identical to the one used by the 1st/2nd gen Carrera Crossfire-e and Vulcan-e. The chargers and battery often come up on ebay. Yosepower use to sell the batteries with the chargers but they don't list them now
