Hi, I've filmed the rear hub in action, both with power on and with power off. Unfortunately I cannot load the videos up to this website... too big. I can stick them in Wetransfer if that's a help?

Hi, There doesn't appear to be any resistance on the freewheel with power off or with power on. The rattling noise, which sounds like a knackered bearing only occurs when the power is on, and the wheel is turning above a certain speed. As the speed drops the noise suddenly stops (as if something is being disengaged) and the wheel continues to spin silently to a stop. There is a definite roughness felt through the pedals while pedaling, but this could be from the pedal bearings. I'm a complete novice at repairing ebikes (none of our local dealers will touch this one, hence my involvement), but if the motor can easily be repaired then I'm happy to have a go.

Many thanks for your response. I have just brought the bike into my workshop... The first thing I've noticed is that the electrics are extensively butchered. It appears that both the throttle and brake sensors have been disconnected. There is an on-off rocker switch which has also been disconnected. The bike was being used in pedal-assist mode only. Once the bike was up on my work stand I noticed that when power was switched on and I turned the pedals there was a rattling, grinding noise from the hub motor. When I turned power off the rattling noises ceased. I am assuming that this is a mechanical problem with the hub motor. If so, is it worth repairing. The owner is happy to purchase a new ebike if this one cannot be repaired. Many thanks Roger

Hi, my neighbour has a Windsor Powacycle which she bought 16 years or so ago. She uses it as her daily commute to work. Last week the power assist stopped working although the battery is charging as normal. Does anyone have experience with this make of ebike that they can share with me before I start taking it to bits? Many thanks in advance Roger

Hi Andy, I followed your advice (over a year ago now) and took the battery in to my local Trek dealer. As it was under 2 years old (just) I got a new battery under warranty... All sorted! Thanks for your advice

Hi, this afternoon I wheeled my Trek Powerfly 5 out of the garage to go for a nice ride in the sun, only to discover that the battery (Performance Line 500) is totally dead. I am not getting anything at all on the Purion display, and when I take the battery out of the frame and plug in the charger nothing happens, no lights, nothing. The charger is working. I have tried switching the battery on and off using the little switch next to the LED lights I last used the bike about 5 days ago and as the battery was down to below 50% had left it charging in the garage. Has anyone else experienced this? Any suggestions? The bike is still under warranty (just) Rog

Could this have been caused by previous overtightening of the QR clamp, and consequent wear on the bearings? A few weeks ago I noticed that the bearings had become quite loose. I've adjusted them and all is well again at the moment, but I'm wondering if I need to change the bearings

Ooooh! Nice!

I'm thinking along the same lines. The front axle lever had worked itself so loose that it wouldn't engage when I flipped the lever over. This has now been adjusted and is now working ok at the moment, but for how long....

I have a Trek Powerfly 5 (2018 model). Recently the rear Rockshox axle has been working completely loose. If I tighten it up as recommended , ie, wind it up until it's tight, back it off half a turn and then push the lever over, then after a few miles on our forest tracks it works loose. If I over tighten it, then the rear wheel binds. Has anyone had the same experience, and if so, how was it fixed?
