Stomp SFR1+ 17KW Electric Bike

Since the dawn of the electric dirt bike era, Stomp has worked hard to find a partner who shares our core values and rider-designed philosophy. This search led to a manufacturing partnership with Rerode. We wanted freeride bikes focused on chassis performance as much as raw electric power — something we feel other manufacturers overlook, with products that tend to be straight-line machines.

With over 20 years of off-road experience, Stomp is owned by engineers, most of whom ride dirt bikes and MTB/jump bikes. Rerode shares a similar setup — founded by a world-class trials rider, with senior staff who ride electric dirt bikes as a hobby. Together, we aim to supply the best lightweight freeride bikes money can buy, starting with the SFR1 and SFR1+.

The primary focus of the SFR1 and SFR1+ is the chassis. Both bikes are super lightweight (59 kg and 65 kg) yet handle off-road like ultra-lightweight motocross bikes. Chassis stiffness and suspension tuning were paramount — especially the rear linkage. We worked tirelessly with Fastace to deliver a chassis that outclasses the competition. No other bike in this class comes close. Steering geometry and how it responds under load was another key focus — a detail neglected by manufacturers who lack the engineering to develop a true off-road chassis.

Both bikes feature powerful hairpin motors, with the SFR1+ producing 550 Nm of rear-wheel torque, powered by a 40 Ah Samsung battery. A larger battery could be used, but it would compromise weight balance and off-road performance. The SFR1+ also features an 18” rear wheel for great tyre choice.

Rider position got close attention. Peg height and placement are often neglected — resulting in bikes that feel unbalanced and awkward. A flat seat design, free of battery bulges, lets the rider move forward for tight turns and railing berms.
