Steeper 69° and shorter travel — happiest descending smooth, flowy trail rather than properly rough or steep terrain.

EMTB Forums verdict
The 2022 Prime is Mondraker's Bosch-powered alloy e-hardtail: a Prime Xtralite 6061 full-butted alloy frame built on Forward Geometry, running a Bosch Performance Line CX Gen 4 (85Nm) motor with an internal removable PowerTube battery. Rear travel is zero, so all the compliance comes from the fork, the tyres and your legs.
The line splits cleanly into trail and lifestyle builds. Prime 29 (120mm RockShox Recon Silver, Maxxis Rekon, 625Wh) and Prime R (120mm Marzocchi Z2, Rekon, uprated to 750Wh and four-piston SRAM G2 brakes) are the trail-focused hardtails. Prime RX and Prime X drop to a 100mm fork and swap to semi-slick Maxxis Grifter rubber for an urban and lifestyle brief; the RX carries the larger 750Wh battery while the X keeps the 625Wh pack.
Across all four it is SRAM SX Eagle 12-speed and MDK-HP1 alloy wheels, so this was always the value end of an eMTB range rather than the boutique end. The bigger 750Wh trims add useful range for all-day riding, and the trail builds are the ones worth seeking out for genuine off-road use.
The Prime is discontinued in this 2022 Gen 4 form, so it is a used-market proposition now. Confirm which battery and fork travel a given bike has before buying, because the 625Wh and 750Wh trims look near identical.
Geometry read
What the numbers mean on the trail
Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.
Size
Setting
Playfulness
70
Short 455mm rear and a lighter build — easy to pop, manual and throw around.
Size balance
73
Rear-long with a planted front in L (FC:RC 1.66) — easy to weight the front and quick to turn, though it can feel light at the back at real speed.
Technical climbing
72
Bosch Performance Line CX Gen 4 and a steep 73.5° seat angle keep the weight planted over the front — a proper winch. 600W of peak power and 85Nm of torque — a strong full-power motor.
Easy to throw around; happiest when you're active on the bike.
Fine at trail pace; it'll feel out of its depth on properly rough, steep tracks.
