Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Mondraker Sly RR Electric Bike 2025 Grey/Black/Yellow

Season:2025

Brand:Mondraker

Code:25-SLRR-GRY/BLK/YEL

Mondraker's most high-tech Stealth Alloy frame ever deserves nothing less than the best.The Mondraker Sly RR Electric Bike's build is a step up if you want to get even more out of your SLY.

FOX suspension provides the 160mm Fox 36 29 Float Performance GRIP fork and a Fox Float X Performance EVOL shock. SRAM Code Bronze Stealth 4 piston brakes with 200mm rotors keep things from getting out of hand on the steeps, and Mavic E-CrossTrail SL 30mm wheels offer the best balance of compliance / rigidity out there.

ONOFF have you covered with a selection of components from the all new S6 range and include a carbon fibre bar, a stem, grips and the Pija seatpost with lengths varying from 140mm to 210mm depending on frame size.


SLY: A SURE BET

After the NEAT and DUNE, SLY is their first mid-power bike to come with a Stealth Alloy frame; all the better to cover the needs of riders wanting to get a foot in the door of the ebike world, or for riders who’d rather not invest quite so much in their light eMTB. That said, from the very beginning they were committed to making SLY’s frame their most advanced full suspension ebike Stealth Alloy frame to date.

TAKE A SECOND LOOK: IT’S ALUMINIUM

It’s Mondraker's most advanced full suspension ebike Stealth Alloy frame to date, bar none. The seamless welds make the joints between the main frame tubes so smooth it’s hard to tell they’re there at all. You’re going to have to give the frame a few taps before you believe it’s really aluminium. It’s the aesthetic of aluminium taken to an extreme.

Mondraker Sly RR Electric Bike Highligts

  • SAME IDENTITY AND FEATURES - SLY’s Stealth Alloy frame demonstrates just how advanced their aluminium technologyis and how finely they can tune it to meet the design criteria demanded by individual models. In the case of the SLY they really wanted to showcase how they can endow an aluminium bike with the same identity and the same features as they do their range-topping carbon fibre frames. The frame carries the same organically angular design as the rest of the Light eMTB 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.

  • THE DEVIL’S IN THE DETAILS - Mondrakertake the same care, and show the same obsession for perfection with the Stealth Alloy bikes as they do with the carbon fibre models.SLY comes with the headtube HHG (Hidden Cable Guide) feature, custom fitted rubber chainstay, downtube and shock protectors, and a UDH mech hanger, as well as an integrated chain guide and two bottle mounts (one of which can be used to mount the range extender).

  • WIRELESS SHIFTING - SLY gets rid of cables where you least want them. To give your cockpit that minimalist look, and to improve shifting overall, they’ve fitted both builds of SLY with SRAM’s AXS T-Type drivetrain, both shifter and cassette, to really up the ante. No longer do you have to spend on carbon fibre builds just to get the latest tech.
