We are incredibly proud to stock the 3T range of e-bikes. The 3T Exploro Racemax Boost GRX is an exceptional electric gravel bike, but also equally at home as an e-road or commuter bike. 3T are famed for making some of the fastest, lightest and best-looking gravel and road bikes on the market and they have extended this into their e-bike range. The 3T Exploro Racemax Boost GRX is designed around being as aerodynamic as possible - everything about the carbon frame suggests speed and it rides equally well with the motor on and off. The specs are top end too: The motor is a Mahale 250W -The bests of the best manufactures consider. Shimano GRX disc brakes and gear set and Pirelli Cinturato Gravel tyres. Finally, the assistance of the motor on such a light gravel bike not only means it is less effort to get up hills, the additional torque means you have more traction and slip less on steep or muddy trails - normally this is a big issue. Arrange a test ride or video call of the 3T Exploro Racemax Boost to find out more... Disclaimer This bike is restricted to 15.5mph of motorised assistance following UK Law.

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, and 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.


Fast flavouring

Introducing, the fastest of the fastest, the quickest gravel bike possible, with aero optimized for 35-45mm WAM tires but even fitting 61mm tires for particularly long rides, this is The Exploro RACEMAX.


The best of the best

Gravel riding is all about tire choice and the 3T Exploro models fit the widest possible tires, up to 61mm. The Exploro PRO and The Exploro TEAM is a Jack of all trades, the RACEMAX is an all-out speed machine while the ULTRA can conquer the toughest terrain faster than any other gravel bike creating it what it is.


Nothing beats the original

This bike pioneered aerodynamics for all of the gravel category, this race tested, and proven, bike gives you the speed you're used to but even faster, especially on those wind swept gravel tracks.

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.

Tim & Catherine (Foldable 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.

Lucy (Mountain 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!

Beth (Road E-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.
