The X1 Spark is built around a 4500W peak mid-drive motor producing 283Nm of torque, fed by a 1728Wh battery pack. That combination delivers serious climbing ability and around 60 miles of range. Adjustable 150mm front suspension, 200mm hydraulic brakes, and moto-style tyres in a 14 inch front and 12 inch rear setup keep it controlled when the terrain gets rough. It is built to UL2849 compliance, the safety standard for electric bicycle systems.

Product Highlights
283Nm of Torque
A 4500W mid-drive motor puts out 283Nm, which is what carries you up steep, loose climbs without the motor running out of ideas halfway.
1728Wh Pack
The 60V 28.8Ah battery is a genuinely large pack, supporting around 60 miles of riding and recharging in roughly 8 hours from the supplied 67.2V 2.0A charger.
UL2849 Compliant
UL2849 is the safety standard covering the electrical drive system, battery, and charger on electric bicycles. Compliance is worth looking for on any high-power lithium product.
Adjustable Suspension
150mm of adjustable travel up front and 75mm at the rear let you tune the ride to your weight and the ground you are covering.
200mm Hydraulic Brakes
Large 200mm hydraulic discs front and rear give consistent stopping power, which a bike with this much torque genuinely needs.
Moto-Style Wheels
A 14 inch front and 12 inch rear tyre setup gives the bike a dirt bike stance and the grip to match on loose surfaces.

Important Information
- With 4500W of peak power and a 50 mph top speed, this exceeds the electric bicycle limits in every US state. It is intended for off-road use on private or permitted land, and it is generally not legal on public roads, bike lanes, or trails. Check your state and local regulations before riding, and note that road use may require registration, insurance, and a licence.
- Wear a full-face helmet, gloves, eye protection, and protective clothing. At these speeds, standard cycling kit is not adequate.
- This is a high-powered machine. It is not suitable for inexperienced or young riders without direct supervision, and riders should build up speed gradually.
- Do not exceed the 350 lb payload capacity, and allow considerably longer braking distances at speed or downhill.
- Charge with the supplied 67.2V 2.0A charger only, on a hard surface away from flammable materials, and do not leave it charging unattended overnight.
- Store and charge the battery within the temperature range in the manual, and stop using it if it is damaged, swollen, or behaving unusually.
- Have the bike assembled and safety checked by a qualified mechanic before first use, and check tyre pressure, brakes, and fasteners before every ride.
- Follow the servicing intervals in the owner's manual. Hydraulic brakes and suspension wear faster under hard off-road use.
