The First Conversion

It Was Just a Rusty Old Bike… Until It Wasn’t

This thing had been chained up outside my flat for over five years. Left to rot in the elements. Thin wheels. V-brakes. Rusty everything. Most people would’ve binned it.

But during lockdown I got the itch. Gave it a full strip down. Cleaned it up. Rebuilt it as an actual pushbike. It was a bit of pride, really — taking something dead and giving it life again.

Then my old e-bike — a proper vintage Thompson Euro Electric — cracked its rear wheel. Couldn’t find a replacement anywhere. Game over.

So I looked at the old thing I’d just restored, sitting there gleaming… and thought: screw it. I’ll convert this one.

I Built It to Pass the Test. Instead, It Nearly Set Fire to My Flat

I didn’t build this thing to be reckless. I built it to go through the proper DVSA process — get it road legal, registered, inspected. All above board.

But that first controller — 26A, came with the kit — packed in after four miles. Just seized the rear motor completely. Locked the wheel while I was out riding. Had to drag it home like a sack of bricks.

So I swapped in a 40A controller, and upgraded the display. Better? Technically. It also nearly caught fire.

No exaggeration — wires melting, smoke pouring out the bag. Four-inch flames wouldn’t have surprised me. Turns out 40mph on a skinny-wheeled, V-brake bicycle is basically a death wish.

That’s when it clicked: this needs more than just a conversion. It needs a full rethink. Stronger frame. Fatter wheels. Hydraulic calipers. A controller that won’t burn your house down.

And that’s how the Panther was born.

The Wake-Up Call

It wasn’t just the smoke and melted wires that rattled me. It was what I realised after: none of this would ever pass inspection.

Controllers in bags? Unlabelled wiring? Zero waterproofing? No compliance documents, no proper speed limiting, nothing. These kits are great fun for back lanes and farm tracks — but for UK roads, they’re a legal and safety nightmare.

I reached out to the DVSA and got the facts. If I wanted this thing approved, it couldn’t just feel roadworthy. It had to be roadworthy. And that meant fixed speed limits, compliant lighting, permanent wiring, CE certifications — the works.

This whole project shifted right there. I wasn’t building a fast toy anymore. I was building a real electric moped. That’s when the Panther was born.

Enter the Panther

I didn’t just want to tweak a few things and hope for the best. I stripped it all back and started again — new frame, new wiring, new vision.

The Panther is built to be legal, fast, and safe. Gone are the dodgy kits and guesswork. In their place: a 1500W hub motor with a fixed 28mph limit, a VESC-based controller for total reliability, and a full set of safety gear — proper hydraulic brakes, lighting, indicators, and those glorious fat 4-inch wheels.

This isn’t a hacked-together bike anymore. This is a serious machine — a road-legal e-moped in the making, going through the DVSA process the right way.

Every wire is labelled. Every component has documentation. Everything is being built with inspection in mind. Because if I can get this through… you can too.

From Shed to Road

Converting a bike is one thing. Getting it approved is another. I wasn’t just building for fun anymore — this had to be road-legal. That meant ticking every single box for the DVSA inspection.

It needed: headlight, tail light, brake lights, indicators, horn, mirror, reflectors, a stand, VIN sticker, and a number plate bracket. Everything labelled, everything bolted down properly. I even had to make sure the speed limit was hardwired and non-adjustable.

Every detail mattered. Tyre markings. Brake compliance. Even where the wiring ran through the frame.

It took weeks. But I got it done.

Credit where it’s due: the DVSA have been absolutely brilliant. Professional, clear, responsive. They don’t mess about — but they’re not out to catch you out either. If you put in the work, they’ll meet you halfway.

So now it’s ready. The Panther’s rebuilt, prepped, and loaded up for inspection.

Will it pass?
