Small, compact, yet simple, the 70cc, is designed as a modular first bike for kids.

After many years of feedback on our best-selling kids bike, we have made a few well overdue changes. The TSK 70-C has received a revamp on all levels, which allows an awesome little package for junior riders to become even better.

Firstly, we have applied our new mini stealth plastics, which give the bike a slick look that appeals to kids and adults alike. It now matches the rest of our bikes in the lineup. Although we thought our old bikes' power was sufficient, here at Thumpstar, we are always looking for that extra thump. The TSK 70-C has an entirely new engine, which is semi-automatic rather than fully automatic, has both an electric and kickstart and overall provides more power, allowing heavier junior riders. Safety on a kids bike is a must-have feature. An emergency lanyard that kills the bike should your child come off, coupled with an adjustable throttle limiter, provides full parental control of the bike.

A great first bike that grows with your young rider, designed to be upgradeable to pro-long service life as your child grows, simply upgrade the forks and rear suspension to the taller option. (Optional taller suspensions package available early 2020.)
