There have been some small silver linings to this whole COVID-19 business, and one of them has been a huge boost to bicycle and ebike sales, as millions of people on lockdown steer clear of public transport and gyms and seek ways to take exercise outdoors in a family-friendly way.

Ebikes are well and truly a mature technology now, and I'm on record as being a total convert. But the fact remains, they're not cheap, and for many folks who already own perfectly good bikes, the option to upgrade to electric assistance using a simple, affordable kit is more attractive. And while some ebike upgrade kits look confusing and complex, this has to be one of the easiest-to-install kits we've seen.

The Unlimited Ebike Conversion Kit, in its simplest form, comes to you with a new, hub-driven front wheel (available in a range of sizes to suit most any bike), a battery pack, a quick-release battery mount plate that screws into the holes where you'd normally fix a drink bottle holder, and a wireless pedal sensor that straps onto your crank arm.

The installation process is simple: first, you drop out your front wheel and replace it with the one in the box, which comes pre-fit with a tire. If you're rocking old-school rim brakes, they'll work just fine, but if you've got a disc brake, switch it over to the new wheel.

Screw the battery mount plate into the frame using the screw holes for a standard bottle holder mount, then position the battery however it fits best. Run a wire up the front fork, clipping it to stay out of the way, and connect it to the battery. Then strap the small pedal sensor onto your crank arm.

That's more or less it. The wireless pedal sensor uses accelerometers and other sensors to figure out when you're pedaling and in which direction, and you get electric assistance at the front wheel. It's available in Euro-legal 250W/25km/h or US-legal 750W/22mph versions, with two different sized battery packs offering either 35 km (22 mi) or 80 km (50 mi) of assisted range.

There's a smartphone app, which you can use to change settings or simply act as a dash if you mount it in a cradle. In a perfect world, and this may be the case, you might also be able to unlock a truly "unlimited" mode free from speed limits. There's the option of a small OLED display that wires back to the battery unit, otherwise you can pedal backwards to change modes through the pedal sensor and go totally dash-free.

Other options include a wired thumb throttle (legal in the US only), and a rear motor version that's more finicky to fit, and doesn't fit all wheel types. Still, with Indiegogo earlybird pricing starting at €449 (US$510), from a company that has previously successfully delivered a similar electrification kit for skateboards, this is an affordable and super-approachable way to upgrade your existing bike and enjoy the benefits of going electric. Deliveries are slated to begin this November if all goes to plan. Check out the kit in the video below.

An elegant solution indeed, with many knobs-on included.
Sadly, the smallest wheel they can do, for now, is for the Bromelton folder, at 16".
I have a pigeon pair of Bickertons, the precursor to all folders, and still the lightest at 10kg, but . . .
They have a 16" wheel, but only at the rear.
The front is just 14", which explains the tiny folded size.
With this kit added, the extra 3kg would have given me eFolders with a weight still less than most other folders are, bare.
But; no 14" avail, and the rear wheel kit is too wide for the all aluminium Bickies.
Back to healthy pedalling then, I guess.
That’s OK. At near 80, a 10kg bike suits me just fine.

I would be very wary of anything offered via Indiegogo. I had a supposed palm size computer that was to be released that never happened and I had pre paid for it along with many other people. Crooks ran off with over 700K and Indiegogo was a complete waste in doing a damn thing about it.

No throttle, no sale.

Mike Vidal: I agree, I lost over $400. on a 3D headphone that had samples, but the guy wasted the money and it never came to be manufactured.

How about regenerative braking, or pedal charging while going downhill or on level ground?

Funny how they cut the EggRider logo from the EggRider V2 display... such a shame, you should give them some credits...

What about "Motor OFF when Braking" ?? I see no mention of that critical feature ...

Indigogo, huh? $500+, huh? No thanks; I'll just get on Amazon, chose one of the umpteen kits already on there, get a hub-mounted motor for the rear tire instead of the front, complete with twist grip or thumb throttle, look up a battery pack, and end up having spent less than $400 with free delivery. Why do these articles always pimp some way-too-expensive vaporware?

They should offer a kit without spokes, rim and wheel so the buyer can have their favorite bike shop lace it to their existing rim.

Does anyone else (apart from me!) remember the SInclair electric bike attachment? It clipped onto the rear wheel under the saddle, and a small wheel pressed against the tyre. Voila!
