Mondraker’s latest Urban Cross alloy e-bikes mash up mountain bike, modern eMTB, and classic city commuter bike tech into a range of three alternative ways to ditch your car for everyday city life. The Prime RX, Prime X & Thundra X look to be a solid set of alt-transport city e-bikes, with enough off-road influence to transition to rides far from town as well…

Designed to get you out of cars, out of traffic jams, and make short trips fun again, the Urban Cross e-bikes rethink hardtail mountain bikes as fully kitted out commuter bikes. Why not ride a bike to work, school, or to meet up with friends with a little pedal-assist support for added motivation!

Each of the three new Mondraker Urban Cross e-bikes is built around a similar versatile alloy hardtail MTB platform with big tire clearance, integrated lighting, and a SRAM SX Eagle 11-50T component build spec that can transition both inside and out of the city. Then, the Prime RX, Prime X & Thundra X each differ in which e-bike drive system they use, how big a battery they get to adapt to slightly different types of riders.

Prime RX

The Prime RX features a Bosch Performance Line CX Cruise BS3(?) motor and a premium Kiox 300 display, all powered by a fully enclosed 750Wh Powertube battery inside the downtube. It also has the shortest fork travel of the line at 100mm from the RockShox 35 Silver TK 29er fork. The RX also gets SRAM G2 4-piston brakes.

Prime X

The Prime X also gets the same Bosch Performance Line CX motor (possibly with an original firmware version?)  but with a Purion display, and it is powered by a smaller but removable Powertube 625Wh battery inside the downtube. It bumps up to 120mm of travel with a RockShox Recon Silver RL 29er fork.

Thundra X

The Thundra X is the only one to be built around a Shimano Steps E7000 powertrain with a mini Shimano display and a 630Wh completely internal battery. But the Shimano system can also be connected with an optional 360Wh Simplo external bottle battery to boost total range by almost 60%. It also gets a 120mm RockShox Recon Silver RL 29er fork.

Tech details

All three Urban Cross e-bikes are built around a lightweight butted 6061 Xtralite alloy hardtail frame with an internal battery, pedal-assist motor at the bottom bracket, short travel RockShox suspension forks.

They all feature full-coverage fenders and rear racks, integrated LED headlights & taillights, kickstands, and come fitted with fast-rolling 29 x 2.5″ wide Maxxis Grifter wire bead tan wall tires.

The Primes get classic Mondraker frame looks with an eyehole behind the headtube, while the still-angular Thundra gets simplified a bit.

No matter which seems to suit you best, all three Mondraker Urban Cross e-bikes look like good options to avoid sitting in city traffic for those shorter commutes, with the persistent opportunity to take a bit of dirt detour on the ride home from work.

Seems kinda dicey to have the rack be braced horizontally with the fender. The other way around, sure, but here if the rack tilts back, the rear wheel could lock up.
