Here it is: the next big step in eBikes. Nukeproof have chosen to build on the Megawatt, refining one of the most successful eBikes on the market.
The new carbon Megawatt was uniquely developed hand in hand with the new SRAM Eagle Powertrain; SRAM relied on test data from this very bike, ridden in the UK, to develop their entry to the eBike drivetrain market. If you want to buy the eBike the new SRAM Eagle Powertrain system was developed to be used with, this is it.
The all new SRAM Eagle Powertrain is a game changer. Using the new Transmission drivetrain, the new motor is low drag and has auto and coast shifting features. Nukeproof have also designed the Megawatt Carbon in such a way that the battery is easily removable.
We at 20Twenty have known about this bike and the new drivetrain for a while. The alloy development mule has been spotted around our local trails - including at the Innerleithen EWS round in 2022 where Nukeproof boss Michael Cowan won the EWS e-100 class on the bike. Since then, it's been spotted being ridden by Nukeproof team riders. It's great to see a bike this being developed under the same riding conditions as we all ride in, all year round.
Megawatt Carbon Frame
Starting with the current alloy Megawatt frame, changing the frame material to carbon allowed Nukeproof to choose where to place material to optimise strength and weight, while keeping the look of the frame similar to the alloy eBike.
Nukeproof have already done their homework with the alloy Megawatt suspension kinematics, so slight tweaks rather than an all out revamp were all that was required to get the best from the new bikes' suspension. The new eBike shares the same family look as the Mega and alloy Megawatt.
Nukeproof tilted the motor in the frame, allowing the battery to be slid out through the bottom of the downtube. The watertight cover at the bottom of the downtube also houses a storage compartment.
Seat tube angle changes between smaller and larger sizes. The higher the seat, the more this makes a difference to saddle offset, particularly important on a bike so capable of technical climbs. The seat tube is long and straight, without suspension pivots, so you can run a long dropper post with no problems.
Lastly, the frame has room for the essential water bottle in the front triangle.
