Trek Rail 9 (2021) electric mountain bike review - MBR

Nov 2020 · Danny Milner

If Tonka did mountain bikes, we reckon they would look a lot like the Trek Rail 9. Pumped up in all directions, the Rail is like a two-wheel linebacker.

Highs
  • Enduro-bike pace and composure coupled with a superb motor

Lows
  • Tyres don’t do the bike justice
