The issue is always not what goes wrong but how the company deals with it. From my experience Wisper should be able to sort you out.

Need to go back to fitting those floppy reflector arms to the back of the bike, the way they flap in the wind draws attention the way the way a rigid reflector doesn't.

Reminds me of the Go-Cycle (?) I love the quote : “To avoid instability when accelerating the electric motor has a sophisticated control system. This ensures that the motor support is evenly built up and unwanted reaction forces can not occur." Must stop those damn high speed wheelies :)

Ah well, back on the road again courtesy of a replacement frame from Wisper ~ had a few hiccups along the way but now rebuilt and off down the road. :)

What should the separation distance be between the sensor and the disk with magnets ? (905SE)

It's no getting the old one off, its more not b*ggering the new one up with a drift :)

I usually approach things with a hammer and drift but thought, for once, I would do it properly !

I do have the original seat post , I have noticed that the later bikes have taller tube on the frame above the weld. Like yours the failure point was at the bottem of the adjuster 'slot' on the frame tube just above the weld.

Thanks David, i will take some photos when i get home and forward them on.

I know it is an old thread but my frame has just failed at the same point, the bike is 2 1/2 yers old but has only done about 2000miles, I am going to have to get on Wisper and see what they can do to help.

Well I have just received my charger and battery back from Steve at Wisper and he reckons that it was just the the charger wasn't making a good contact when it was plugged into the battery. Anyway he returned it charged and the bike runs well so assuming it charges when I've run it down a...

Why not just put a big flywheel in store energy :D
