I Removed My Ebike’s Speed Limiter… Here’s What Happened
I Removed My Ebike’s Speed Limiter — Full Speed Controller Upgrade Tutorial (Works on Any Ebike)
Surron electric motorcycle is not the only capable electric bike.
Sick of your ebike being capped at a snail’s pace? In this one I rip out the stock speed controller and show you exactly how ebike speed limiter removal is done — the proper way, not the shunt mod everyone talks about.
Rasta on a Ride here, fitting a Surron style electric motorcycle speed controller straight onto a regular electric bicycle. We’re upping the amps and current on the controller to unlock way more top speed from the rear hub motor — and I’ll show you why swapping the ESC (electric speed controller) beats a shunt mod every time.
What’s covered in this video:
Full electric speed controller installation
Speed limiter removal, step by step
How to wire a throttle
How to wire your speed controller to the motor
Real POV ride review after the upgrade with a real bike rider
This works whether you’re running a 36v EAPC ebike, a 48v setup upgraded to 52v, or a full 72v electric motorcycle like the Surron. Same logic applies to electric scooters too — if you’re after “how to make any escooter go faster,” the speed limiter removal method here works the same way.
⚠️ Legal note: removing a speed limiter or upgrading power beyond EAPC limits can take your bike outside UK road-legal specs. Know your local ebike law before you ride it on public roads.
