Hi all. I have been asked to re-pack a pair of these old Yamaha bikes. The gentleman is fully aware that cost is likely to be more than the bikes are really ‘worth’ and he does have a pair of folding SeaGo bikes too, but they have had them for 18 or so years and very fond of them. He has not...

Hi Just been asked to try and sort an Impluse 2.0 middrive bike. Seems 50cycles don’t stock parts now, and Kalkhoff tell him to go to his dealer, which is 50cycles. So he is stuck and came to me Problem is the left hand switch unit is missing /broken and all I have are the 5 or 6 wires...

I have just been asked to have a look at a Cytronex kit fitted to a Canondale. Basics...it is dead..does not provide assist. Not seen one of these before I am assuming a geared motor ? so if i were to spin it backwards i was expecting it to provide resistance, turn the motor backwards, and...

I have only managed to find two threads relating to this bike, both of which were dead ends. Looks like the Fast4ward Edge folder is almost identical to the A2B Kuo..but I can not be sure. The Edge has a handle bar display, but I can not see one mentioned in the Kuo pdf manual. Someone...

I have not stripped it to measure accurately but from a general viewing of this 8 speed hub, with its odd lacing pattern it appears that the holes that are drilled on this hub seem to be spaced 10 degrees apart. 12 holes each side, one side offset by one hole to the other side. Shimano...

A friend has just bought this for £150 second hand. Possibly made a bit much for it, but seems ok. I am sure this is the same motor as fitted to the Thompson Euro Tourer..that I have played with before..so the motor is BLDC hall effect sensor motor. But anyone have details of controller...
