Revvi Electric Bike Buyer’s Guide – Find The Right Revvi
Choosing the right Revvi electric bike isn’t just about age.
Children grow at different rates, and two riders of the same age can have very different heights, inside-leg measurements, confidence and riding experience.
That’s why at CMW Bikes, we recommend considering height, inside leg, age, experience and the type of riding your child will be doing before choosing a bike.
📏 Remember — Height Isn’t Everything
These height ranges are approximate CMW Bikes sizing guidance, not strict limits.
A rider’s inside-leg measurement, weight, confidence and previous riding experience are all important when choosing the right bike.
The rider should be able to comfortably control the bike and reach the controls.
If you’re unsure, get in touch before ordering and we’ll help you choose.

Revvi Size Guide

Please use these figures as a guide only. Rider height, inside leg, weight and experience should all be considered.
Safety First 🛡️
Revvi bikes are designed for appropriate off-road/private-land riding.
Before allowing your child to ride, make sure they have appropriate protective equipment, including a properly fitted helmet, gloves, suitable footwear and additional protection such as knee and elbow protection.
Start at a lower speed and allow the rider to become comfortable with the bike before increasing the speed.
Never allow a child to ride beyond their ability. Adult supervision is recommended.
Always make sure you have permission to ride on the land and check the rules that apply to the specific model and location.
