Q: Good evening. I was referred to your shop from someone on a forum, and I’m hoping you can help me. I’m looking to convert my Trail 8 bike to a rear-wheel electric. I have very little understanding of mechanics, bike parts, and measurements so finding a kit that is the right size for my bike has been very difficult. I am confident that I can install the kit if I have the right one. If you don’t mind could you please have a look at my bike’s specifications and tell me which specific kit will fit my bike? I’m very motivated to purchase one. Thank you!
A: Not sure it’s 27.5″ or 29 inch? (27.5 inch rim is smaller than 29 inch rim)
If tire size is 29 x 2.25″ — All of our 29 inch hub motor kits are fit for this tire.
How to choose bike conversion kit?
1. Check tire size, there is some words on tire (from picture,we can’t find tire size)
For example: if there is 29 x 2.25″
29 inch wheel size, 2.25″ is tire width…
All of our 29 inch hub motor fit for this 29 x 2.25″ tire
2. check front or rear fork width
For example: the dropout of this bike is 135mm (can’t find this info on your link)
All of our rear hub motor kits with max 7 speed fit for this 135mm rear dropout
(If you hope install 8 speed,9 speed.. the dropout should be a little larger than 135mm, if fork dropout can be a little large, to be 140mm, install 8 speed,9 speed on our rear hub motor is no problem)
Generally just 1 & 2 both fit for.. mount this hub motor kit to your bike is no problem.
(Nearly all of this kind bike’s rear dropout is 135mm or a little larger.. install is no problem)
21 speed is okay.
Front is 3 speed, rear is 7 speed..
Our 29 inch rear hub motor with 7 speed is fit for standard 135mm dropout.
(Some bike rear has 8 speed or 9 speed..)
Q: Ah okay I think I get it now. Sorry for my questions this is out of my knowledge area. So it looks like https://www.leafbike.com/products/diy-bike-conversion-kit/29-inch-48v-52v-1500w-rear-wheel-electric-hub-motor-kit-1065.html is going to be the one for me. I’ll make sure on that fork size tomorrow and check with my bike shop if they think the dropouts are sturdy enough. Just a couple more questions – do you have a 48V battery recommendation? And there an installation guide with the kit?
