My Take as a British MX Rider
The Revvi 20" is the most capable bike Revvi make, but it still keeps the smooth and controlled feel that makes the range so popular.
For taller or more confident riders, the extra size, 800W motor and stronger battery make a noticeable difference compared with the Revvi 18.
If your rider has outgrown the Revvi 18 or needs the largest Revvi platform, the Revvi 20" is the one to go for.
