BMC Twostroke 01 ONE mountain bike hardtail in review – better than a gravel bike?

Feb 2022 · By

A hardtail on test at GRAN FONDO? That's right. We couldn't leave the BMC Twostroke 01 ONE – the pioneer of a new hardtail generation – out of our concept group test of gravel and mountain bikes. Find out how versatile it really is here.

Highs
  • High level of traction, comfort and safety
