Mondraker was, perhaps, prescient with their forward stretched geometry and super short stems, putting them on some wicked looking hardtail and full suspension mountain bikes years ago. Now, they’re putting Forward Geometry on a new performance oriented hardtail called e-Prime.
Based on their Prime “traditional” mountain bikes, the e-Prime adds a Bosch pedal-assist motor to their Stealth Carbon frame with flat, bump absorbing seatstays. And it gets 27.5+ tires. Check out the details and video below…
Designed as race e-MTB (there are e-bike races in Europe, just wait, they’ll be in North America, too. No, not motorcycle races, you’ll still have to pedal), the e-Prime grabs all of their race-oriented tech and just modifies the frame to accept the motor.
The Bosch Performance CX system gets a 500 W/h battery, which mounts to the downtube where a water bottle normally goes. The system provides four levels of assist (50% / 120% / 210% /300%), helping out up to 25km/h (15.5mph). That’s slower than most pavement-oriented e-bikes, likely thanks to revised gearing and electronics optimized for off road riding. It also gets an off-road specific protective plate surrounding the front and bottom.
Other than that, the frame looks much like their standard hardtails, with cleanly routed internal cables and hoses…
…and stealth dropper post.
Fitted with a 27.5 x 2.8, there’s still plenty of clearance for up to a 3.0. Internal rim width is 35mm, and it uses Boost hub spacing.
It comes in S/M/L/XL frame sizes and will have four spec level options. Pricing TBD.
