Trying to choose between the Revvi 18 and Revvi 20? Both are excellent kids electric bikes, but they suit slightly different riders.
The Revvi 18 is usually the best progression-focused choice for confident young riders moving up from smaller bikes. The Revvi 20 is the better fit for older, taller or more confident riders who want a larger long-term platform.
Revvi 18 and Revvi 20 bikes are in stock now with fast UK delivery from Garland Powersports.
Quick Answer
Choose the Revvi 18 if your rider is aged around 8–11, stepping up from a 16” bike, or still building confidence.
Choose the Revvi 20 if your rider is older, taller, already confident, or needs a larger bike with more room to grow.
For most riders, we would lean Revvi 18. For taller or more advanced riders, the Revvi 20 makes more sense.
My Take as a British MX Rider
I see the Revvi 18 as the sweet-spot progression bike. It gives young riders a proper step up without going too big too soon.
The Revvi 20 is the bigger platform for riders who are already confident and ready for more bike underneath them.
If in doubt, I’d usually choose confidence and control over maximum size.

Our Verdict
If I was choosing for most riders, I’d lean Revvi 18.
It is a strong progression bike and often the safer fit for riders stepping up from smaller models.
The Revvi 20 is excellent for confident riders wanting a bigger platform and more long-term use.
The mistake is usually sizing too big too early — not too small.
