The primary focus of the SFR1 and SFR1+ is the chassis. Both bikes are super lightweight and 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.

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.

SPECIFICATION

This kit comes with everything you need to mount most 12x142mm through axle mountain bikes on your KICKR.

Note: The KICKR is not compatible with the through axle itself; instead, we use this adapter kit to secure the bike in place. Please watch the installation video before attempting to install yourself. This is for 12x142mm bikes only. Not compatible with 12×135, 12×150,

This mounting kit includes extra mounts so that you can take full advantage of you PROTKT while riding, running, or any other fitness activity.

The Wahoo Key connects your iPhone to any ANT+ fitness sensor such as heart rate monitors, cycling speed & cadence sensors and power meters. It can also be used to pull data from an ANT+ GPS watch into an iPhone App so that real-time activity information is in the palm of your hand… or strapped to your arm!
