DESCRIPTION
Looks like a road bike, rips through rough terrain, and hides a power boost inside. The fastest gravel bike - only faster.
The Exploro Racemax Boost e-bike is perfect for gravel & all-road riding. It’s light yet tough, agile yet planted and fast yet fun.
This makes the Racemax Boost a great range-extender on your gravel adventure. Or it can help you keep up with faster friends on road and gravel rides. It can even be a great commuter: arrive without a sweat, integrate an adventurous workout on the way home.
The Racemax has won many awards as the fastest performance gravel bike on earth. The Racemax Boost (left) uses the same frame - 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 add one more: extra power whenever you need it.
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-35 system offers all three.
The Exploro Boost is available in both dropbar and flatbar versions to meet your needs.
All ex demo bikes are in near perfect condition, come with a full manufacturers warranty and have done less than 50 miles.

There is a lot to consider when buying a new electric bike, but that's why we are here. We want to answer your questions and ensure you feel confident you're buying your ideal e-bike.
Tim & Catherine (Foldable e-bike)We have taken the bikes out twice so far, around Salisbury, and have really enjoyed them, as well as the interested looks from people as we go by. I had mentioned that our road is quite a long hill rising at a good height and that we live at the top. Level 3 is fine, Level 4 easy, while Level 5 is amazing! Thank you again for all your help. We have been telling people about you and The Cycle Company and will certainly continue to do so.
Lucy (Mountain E-bike)Amazing!!! I love bike riding!!! Cheesefoot hill no problem ... really loved the whole ride and kept up with the horse and left my husband and son for dead!!! Great bike great service dead chuffed!!! Thanks.
Beth (Road E-bike)I tried several e-bikes before settling on the Peak Trail 1 ELS – as soon as I had the test ride I knew it was the right bike for me, it was like driving a Jag vs a Ford! It’s so comfortable and smooth. It was a big benefit to use The Cycle Scheme to pay too. Thanks to The Cycle Company for all your help and advice and for seeing me on a Sunday!
Guy, (Full Suspension E-Mountain Bike)Wow! I love my bike. Everything about it is classy, it looks great, and the motor is incredibly powerful, and the specs are superb. I’ve been flying up the hills and getting so many more downhills each ride. I’m the envy of my Mtb buddies! Thanks for all your help.
