Boost Models
Look super clean, rip through rough terrain, hide a power boost inside. Same handling capabilities of RaceMax & Ultra platforms- only faster.
From exploration to commute
All the 3 models are light yet tough, agile yet planted and fast yet fun, making them a great range- extender on your gravel adventure. Or they can help you keep up with faster friends on road and gravel rides. Or they can even be a great commuter: arrive without a sweat, integrate an adventurous workout on the way home.
The Racemax Boost e-bike is perfect for fast gravel & all-road riding.
The Ultra Boost e-bike is perfect for tough gravel and offers additional battery range compared to RaceMax Boost.
The Ultra Boost Urban e-bike is perfect for commuting & gravel riding offering the same battery range of Ultra Boost.
Same award-winning frame
The Racemax Boost, Ultra Boost&Ultra Boost Urban use the same award winning RaceMax and Ultra frames respectively - all electronic parts fit neatly inside without the need for bulkier tubes or visible cables. So you keep all the performance features of the original Racemax and Ultra frames and add one more: extra power whenever you need it.
Best e-bike drivetrain
Our goal was to keep the fun and flow of a fast, agile gravel bike, not to build a motorcycle with pedals. That means the system has to be very light, offer a very smooth power build-up & create no drag when turned off. In the end, 3T’s customized Mahle X-20 system offers all three.
Ultra Boost - Dropbar or Flatbar
The Ultra is available in both Ultra Boost (with dropbar) and Ultra Boost Urban (with flatbar) versions to meet your needs.
