Hi, I have a specialized bike (expedition) I would like to add your kit to. Other vendors of these kits all recommend not using their kits on aluminum framed bikes as the drop outs will crack or break. Your kit does not mention this. Please comment, I am anxious to order your kit.

thx

Hi tjhaine,

This is an excellent question and a common concern.

The bottom line is that it is best to use a steel fork with any electric motor for it's rigidness and durability. Any fork used that is not steel does pose the risk of cracking, bending of breaking in some manner. The frame of the bike is less important than the fork (where your front wheel goes). If you can swap out your front fork, something a local bike shop can easily do, this is generally recommended.

With that said, we have many customers who use their Hill Topper with an aluminum fork. While we don't recommend this, we have heard of no failures with the electric motor causing damage to the fork of anyone of our customers. We recommend that if customers do choose to use the Hill Topper with a fork made of any material other than steel, that they regularly check the fork for any cracking or bending before riding.

Do other people have experiences with their bike that they want to share?
