Subtitle: How a 40mph fire hazard turned into the Panther — and why I’ll never build like that again.
🔥 I Didn’t Start With a New Bike
The first build — the Ninja — was a rust bucket I’d left chained up outside for over five years. Exposed to the rain, wind, snow — the lot. It was seized solid, covered in moss, and had tyres so flat they cracked when I touched them.
But I brought it back. Bit of elbow grease. New cables. Got it rolling.
Then I bolted on a 1500W rear hub motor and thought, “Let’s see what it can do.”
⚠️ From Scrap to 40mph Fire Hazard
First controller? 26A.
It lasted less than a week before it fried.
Second one? 40A. That’s when it got stupid.
It took the bike up to 40mph.
40mph… on a bike that had V-brakes and tyres from the last decade. It was like trying to stop a freight train with a stick.
Thin wheels. Old bearings. A frame that had been rusting for years.
And I was holding on like it was fine.
💥 The Warning I Didn’t Ignore
The controller was stuffed in a cloth bag under the seat — cheap, unventilated, and cooking itself before the ride even started.
I even filmed myself saying:
“This controller’s gonna get hot in that bag… could be a fire risk.”
Ten minutes into the ride, it was more than a risk.
The throttle was glitching. The wires were melting. Smoke was seeping out the top.
If I’d parked the bike and walked inside, I’d have come back to a full-blown fire.
🔄 That Was the Line
That moment wasn’t about fear — it was about clarity.
I saw what would happen if someone less experienced built the same way. A teenager. A commuter. Someone chasing TikTok likes.
These bikes aren’t toys. At 40mph, with lithium batteries and no regulation, they’re a death trap waiting to happen.
So I stripped it all back and started again.
🐾 Warrior Cycles Was Born
The Panther is what came next.
- 4-inch fat tyres for real grip and stopping power
- Hydraulic disc brakes — not V-brakes
- VESC-based controller — rock solid, configurable, safe
- Permanent 28mph limit — no toggles, no “just bump it up”
I built the Panther to be bulletproof. Something that could pass DVSA inspection and still give you that raw e-bike grin.
🚨 This Isn’t Just My Story
Almost half of all property fires linked to e-bikes or scooters in the UK come down to the same problem I had — cheap parts, bad setups, and corners cut.
No crash. No impact. Just heat, poor wiring, and no plan B.
The Ninja nearly went up. The next one might take a flat with it.
🛠 What’s Next
The Panther is now legal. Fast. Safe. Inspected.
The Ninja? It’s going back to the drawing board — built the way it should’ve been from the start.
Because this isn’t just a project. It’s a mission.
