2026 Revvi Comparison Guide

Revvi 18 vs Revvi 20

Trying to choose between the Revvi 18 and Revvi 20? The Revvi 18 is the manageable step-up option for riders around 8–11 and 130–155cm. The Revvi 20 is the larger, more powerful platform for riders around 10–14 and typically 135cm+.

Fit and confidence matter more than age alone—do not size up purely for maximum speed.

Quick Answer

Choose the Revvi 18 if your rider is aged around 8–12, 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.

The Revvi 20 takes everything up a level with more power, more size and a bigger-bike feel.

  • More powerful 800W setup
  • Larger frame and more stability
  • Better for taller riders

Better for riders stepping up and still building control.

Revvi 20

Better for taller, older or already confident riders.

Which Should You Choose?

Choose Revvi 18 If...

  • Your rider is moving up from a 16” bike
  • Confidence is still developing
  • You want the safest progression route
  • You want the sweet-spot bike in the range

Choose Revvi 20 If...

  • Your rider is tall for their age
  • They are already very confident
  • You want a longer-term bike
  • You want more size and performance

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.
