Review: Prime Thunderflash - A Standout Enduro Bike

Mar 2023 · Matt Beer

Where has this bike been hiding? Prime has built a superb enduro bike that can muscle up against the heavy hitters in this category while descending but doesn't land flat-footed when the trail requires finesse.

Highs
  • Strong, deep rider position doesn’t hold back descending

  • Clean design with sturdy frame and hardware

  • Combo of supple suspension and moderate head angle keeps it agile in slower, technical zones

Lows
  • Limited frame sizes

  • Convoluted cable routing

  • Underpowered brakes hold back the bike's capabilities

The brand new Prime Thunderflash RSX 2021 in review – Rolling thunder on the trails?

Apr 2021 · Peter Walker

New polish brand, Prime, introduce the brand new Thunderflash. We already had the exclusive chance to put it to the test!

Highs
  • Lots of mid-stroke support from the suspension

  • Efficient enough to forgo the climb switch

  • Intuitive, precise handling

  • Great looking frame with smart features

Lows
  • Small weaknesses in the components

  • Brake line rattles on the fork crown

  • No size S to accommodate small riders
