8mm_sprocketsWe are always happy to help sort out gear ratios for our customers, just e-mail or ring us up for any help.

We offer a boring/reaming service which starts at 2.50, please contact for individual price.

We can also put grub screws in with prices starting from 2.50, please contact for individual price.


To give an idea for gearing we find that if you fit an 8T to the motor and as large as you can to the axle on a single reduction you almost always end up around 8MPH
