Wisper 905se Forks

[Amoto65]

Hi folks, having owned my 905se for 10 months now i have come to the conclusion i need some suspension forks, due to the state of the roads in Cheshire and my weary old bones. Will i need a specific type of forks for an ebike due to weight? (the bikes not mine) Suggestions please. Cheers Steve.

Not sure you can fit sus forks to a solid fork frame. The suspension fork would be longer so the front end would be kicked up. This alters the angle of the steering head and does God knows what to the handling. Also there would be extra strain on the forks because the loading on them would be further out of vertical than they were designed for.
When I looked into this for my old hybrid, I ended up buying a Carrera and converting it with a hub kit.

Hi Steve
I think the rigid fork has a longish collar above the above the fork itself but below the steerer, while the supension fork they fit as an optional extra (a Suntour NEX) does not, leaving room for the sliding part of the fork to move without lifting the front of the frame or changing the geometry much when the fork is extended.
If you post on the Wisper clinic forum, I am sure David who seems very helpful would give you definitive answer. They might even be able to sell you a replacement suspension fork, that you then know ill fit.
Cheers

Suspension fork can definitely be fitted on a 905SE.

It is even offered as a £100 option on the Wisper website.

I stand corrected

Yep I can confirm it's an easy change.

All the best, David
