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!\u00a0<\/p>\n
A: Not sure it’s 27.5″ or 29 inch? (27.5 inch rim is smaller than 29 inch rim)<\/p>\n
If tire size is 29 x 2.25″ — All of our 29 inch hub motor kits are fit for this tire.<\/p>\n
How to choose bike conversion kit<\/a>? 29 inch wheel size, 2.25″ is tire width… 2. check front or rear fork width
\n1. Check tire size, there is some words on tire (from picture,we can’t find tire size)
\nFor example: if there is \u00a029 x 2.25″<\/p>\n
\nAll of our 29 inch hub motor fit for this 29 x 2.25″ tire<\/p>\n
\nFor example: the dropout of this bike is 135mm (can’t find this info on your link)
\nAll of our rear hub motor kits with max 7 speed fit for this 135mm rear dropout
\n(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)<\/p>\n
