80cc Bicycle Engine Kit,2 Stroke Motorized Bike Kit,Petrol Bikes Motor with Digital Computer for 26-28" Bikes

I wouldn't recommend the 110 kit due to inferior cylinder port timing. The 100 is better but the 80 has the best port timing of the 3. Good luck https://www.amazon.com/dp/B0D9QCC65N/ref=sspa_mw_detail_4?ie=UTF8&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWw
