Some models need specific gearing and power requirements to ensure a reliable start.
We ask that you supply as much detail as possible in regards to your ride when placing an order. This ensures we build your unit as efficiently as possible to meet your needs.
If you have multiple types of bikes to start, please notify us and we will attempt to find a happy medium for you.
Sorry for the delay- I have been busy with work and haven’t been racing for a couple of weeks. Anyway, went over the Easter break and it is working beautifully with the 13 sprocket - given the bike is absolutely straight and the tyre doesn’t touch either sidewall and the battery is charged to the max. So thank you guys very much for that and your support- it has been a refreshing experience to deal with guys who actually care for a change!!!!
