Legal Speed Limiter

Make Your E-Bike Road Legal in One Flick

The Legal Speed Limiter is a compact handlebar switch that caps your electric bike at 15.5mph (25km/h), the maximum assisted speed allowed for e-bikes on public roads in most countries worldwide. Flick it on and your conversion kit is held to the legal limit. Flick it off and you have your full power back for private land and off-road riding.

It's built to work with any conversion kit, so whether you're running a 48V 1500W, a 52V 2000W or our 72V 3000W Beast, one switch gets you road-ready.

Why You Need One

A powerful conversion kit is brilliant fun, but in most countries worldwide, e-bikes on public roads are legally limited to an assisted speed of 15.5mph (25km/h). Ride faster than that on the road and your bike can be treated as a motor vehicle, which can bring insurance, registration and licensing requirements. The Legal Speed Limiter gives you a simple, reliable way to keep your bike within the limit when you need to, without giving up the performance of your kit for the rest of your riding.

Key Features

• Limits your bike to 15.5mph / 25km/h: the legal assisted speed limit for e-bikes in most countries worldwide.
• Works on any conversion kit: compatible with all VoltRushKits conversion kits and other brands of hub motor kit.
• Two modes, one switch: ON for legal road riding, OFF for full power off-road or on private land.
• Clamps to the handlebar: sits right under your thumb so you can switch modes without taking your hands off the bars.
• Clear markings: the standard O / I rocker makes it obvious which mode you're in at a glance.
• Weather-resistant build: tough black housing with a sealed rubber-ringed switch, made to cope with rain, mud and vibration.
• Simple two-wire connection: a straightforward two-core cable (blue and red) that connects into your kit's wiring.
• Compact and discreet: a small, low-profile housing that looks like a stock part of your cockpit.

How It Works

The switch is wired into your conversion kit and mounts on your handlebar. With the switch set to ON, your bike is limited to 15.5mph (25km/h). With the switch set to OFF, your kit runs at its normal full speed. That means one bike can be a legal commuter during the week and an off-road monster at the weekend, simply by flicking a switch.

Easy to Fit

• Clamps onto a standard 22mm handlebar with the built-in clamp and a single screw.
• Connects with a simple two-core cable to your kit's wiring.
• Fits in minutes with basic tools.
• No need to replace your controller or display.

Who Is It For?

• Riders who want to use their conversion kit on public roads and cycle paths within the law, wherever they live.
• Commuters who want a legal bike for the week and the option of full power on private land.
• Anyone running a powerful 48V, 52V or 72V kit who wants a simple way to stay compliant.
• First-time converters who want peace of mind when riding in public.

Please note: in most countries worldwide, the legal assisted speed limit for e-bikes on public roads is 15.5mph (25km/h). Exact limits vary by country, so riders are responsible for complying with the laws where they ride. Use the switch in the OFF position on private land only.
