Description :
The 3T Exploro RaceMax Boost electric bike is perfect for gravel and all-road. It's light yet robust, agile yet stable, fast yet fun. This makes the Racemax Boost an excellent ally for extending your adventures. It can also help you keep up with your faster friends on the road or gravel paths. It can even be a great daily commuter: arrive at the office without breaking a sweat and launch an adventurous workout on the way home.
The Racemax has won numerous awards as the world's fastest gravel bike. The Racemax Boost uses the same frame; all the electronics fit perfectly inside without the need for bulky tubes or visible cables. So you keep all the performance features of the original Racemax and add another: extra power when you need it.
3T's aim was to retain the fun and fluidity of a fast, agile gravel bike, not to build a bike with pedals. This meant that the pedal-assist system had to be very light, offer a very smooth build-up of power and create no drag when switched off. The Mahle ebikemotion X-35 system, customized by 3T, offers all three.

*The length of the RaceMax fork is equal to that of a standard road bike. This head tube length can therefore be compared with that of road bikes. To compare this data with gravel bikes fitted with standard gravel forks, deduct 25 mm from these "road" head tube lengths for a more appropriate comparison.
