Mondraker SLY - Perfectly Balenced, Impressively Powerful
Mondraker's dedication to pushing the boundaries of e-MTB design is evident in the SLY 2025, a full suspension electric mountain bike that sets a new standard for aluminium construction. Through advancements in their Stealth Alloy technology, Mondraker has achieved a remarkable feat: an e-bike that rivals the performance of their carbon fibre models, all while maintaining a featherlight weight of under 21kg. The SLY's striking design, trail-ready suspension, and powerful Bosch Performance SX motor combine to create an exceptional lightweight EMTB experience that defies expectations.
ALUMINIUM, POWER AND LIGHTWEIGHT
Mondraker are convinced that SLY will become a reference point for riders looking for a truly versatile e-Bike. Since their inception, versatility has been a key point of our mid-power NEAT and DUNE models, as well as our full power CRAFTY; and SLY was never going to be the exception. SLY, tipping the scales at under 21kg, gives you the same performance from an aluminium frame as you’d expect from our full suspension, carbon fibre framed bikes.
STEALTH ALLOY FRAME
SLY’s Stealth Alloy frame demonstrates just how advanced our aluminium technology is and how finely we can tune it to meet the design criteria
demanded by individual models. In the case of the SLY we really want to showcase how we can endow an aluminium bike with the same identity and the same features as we do our range-topping carbon fibre frames. The frame carries the same organically angular design as the rest of the Light e-MTB range, the NEAT and DUNE, yet with the added bonus of the aesthetics of aluminium. The welds join the alloy tubes so seamlessly they’re almost
invisible.
BOSCH PERFORMANCE SX
SLY builds on the compact, light and punchy Bosch Performance SX with its 55Nm of torque and 600W of peak power. It’s the same motor we chose for the DUNE and combined with its 400Wh integrated battery it offers a very similar riding experience and performance to the NEAT and of course the DUNE. Available in two build options, R and RR, and with both of them weighing in at under 21kg, SLY takes the crown as our lightest full suspension 150mm travel aluminium e-Bike, regardless of category. Which, together with the performance of the Bosch SX motor and its optional 250Wh range extender, makes it the MPV for anyone looking for a lightweight aluminium enduro e-Bike in today’s market.
