Electro & Co's ETM RTR is a pit bike on 14/12-inch dirt wheels, with a bigger XL on 17/14s. The Rizzler is a mini bike with a lower 27 in seat. RTR batteries come out without tools.
How to choose: Pick by size first: the Rizzler has a 27 in seat, and the RTR XL fits taller riders with a 32 in seat. Then compare power: Lite 5 kW, Sport 8 kW, and Alpha 18 kW.
Specs are as Electro & Company publishes them. Real-world range and speed depend on rider weight, terrain and mode.
About Electro & Company
Electro & Company Inc. is a California company. Its mailing address is in Cool, California. It started out selling electric conversion kits, including its emx® bolt-on motocross kits and upgrade kits for Razor bikes.
The ETM™ RTR is Electro & Company's first line of electric pit bikes designed fully in-house, drawn up in its California shop. The line runs from the 5,000-watt RTR Lite to the 18,000-watt RTR Alpha. All use a hot-swappable battery that comes out without tools.
The 2026 RTR Sport replaced the original ETM RTR. It adds a new Revolver motor, a 420 chain, a reinforced swingarm and peg bar, and improved brakes, battery management and cooling. The Rizzler mini bike, built on the same platform, arrived in November 2025.
Electro & Company states: "Bikes sold by E&C have a 30-day limited warranty against defects, a 6-month limited warranty on powertrain parts and for the first year a 30% discount on powertrain parts."

55+ mph, with 8,000 watts max output and three power levels.
30–50 miles on the stock 72V 25Ah battery.
1–4 hours depending on the charger. From empty, Electro & Company estimates about 5 hours on the included 5A charger and about 2 hours on a 12A charger.

Electro & Company does not publish a limit for the RTR Sport. It says the ETM RTR powertrain was designed around a 180 lb rider and the frame can support up to 225 lb.
