Skarper E-bike Conversion Kit (2022)

It would seem that electric support systems for a bicycle are already well established: this is a motor-wheel, a central motor that turns the transmission and systems that rotate the wheel through friction. But no, the English company Skarper has introduced another option for fast electric conversion for a bicycle. The technology is called DiskDrive and it spins the rear wheel through a brake disc.

The electric drive system from Skarper is quick-detachable, mounted on the left chainstay of the bicycle frame. True, the rear brake rotor must first be replaced with a proprietary one. The entire system can be quickly removed with a lever to charge the built-in battery. The total weight of the device is only 3.3 kg.

The device with DiskDrive technology is unitary, in one case there are:

-BC electric motor 250 W
-Lithium battery 202 Wh
-Rear red light
-Status indicators
-Brake disc drive system
-Control sensors

The maximum speed with electric assistance is 32 km/h, the built-in battery lasts up to 60 km of pedaling support, and it charges in just 2.5 hours.

To efficiently distribute the power of the motor, Skarper added proprietary Dynamic Climb™ technology. The bottom line is tracking readings from sensors (speed, acceleration, slope) and an algorithm for effective motor assistance.

The novelty will appear on sale next year, the estimated price will be 1220 US dollars.

It can't get anymore compact than that great innovation for the cycling world that's a great thought in a small way good thinking.

[jackbrown]

Fact that it utilises your own bike i think is defo a game changer . I cant imagine Hoy putting his name on a Dud ...will definitely look out for it .

[garymitchell]

Can't find any explanation anywhere on how it works in detail, which is a concern. And the light weight strongly suggests there isn't much battery, with the distance range correspondingly relatively short, which is fine for town use but not much else. But my main concern is the predicted extremely high cost which is a big barrier. The components can't justify it, so it's pure marketing. Why not buy a genuine e-bike and get something specifically designed and with a much longer range. Good idea but currently with severe limitations, so it's a no from me.

Can't wait for a cheap Chinese version of this thing

[nubatman]

I'm looking at that and only seeing flat area usefulness. It's probably pushing a 300w motor and 2000mAh battery. With that pricetag I will definitely shy away.. Expecially since I live in a hilly town. It's an interesting concept, but just does not seem worth it at all.

[melomelon]

I seen the price and you be better off buying a whole new ebike at that point

[astrojack]

Your lucky if you get to test this I want one for my Mtb

[FHRider-om]

Daft question, but how do you control it, is it intuitive?

It is a great product, I loved it, I would like to know about the brake to stop, I know it does have, but never mentioned how it is working, it would be great to know, good lock on your invention

[harvajanshing]

I also want.this motor where it available..bro...

[RelakS__]

Really? You make a video about a product, and don't provide a link to it?

[keep-going]

Can this be used on a full suspension mountain bike.

[NWforager]

i'm guessing this system is not very powerful or fast . interesting all-in-one design tho. for that price i'd go with a mid-drive kit like bbs02

[pjay]

What's the great thing about being able to remove it? I don't see why you want to do that. They're inevitably limiting battery size for no apparent benefit.
Better to leave the motor on and just have a bigger removable battery.

[steevkeyes]

This might be a game-changer product. In general, I like it allot ... but I have reservations about the electrical power transfer mechanism, and the attachment mechanism:

I don't understand how power is transferred from the internal motor to the external disk rotor. I understand the disk rotor is Skarper product. By visual examination, I am guessing it is magnetic induction drive across the void gap between the external housing unit and the rotor disk. I wonder how mechanically efficient this power transfer process is?

As an engineer myself, I am somewhat concerned about the attachment fittings. The hanger fitting that is strapped onto the bike's rear stay seams flimsy. I fear the Skarper unit may be prone to lateral play. But, this can easily be tested by Skarper and enhanced in version 2.0.

[amandatran]

skarper cost $1200 and I was like nah, I'll get a full ebike at $1500 plenty out there, why I have to pay for this and then buy a bike to be able to ride it. To get a decent bike would cost another $3-$500 dollars plus $1200 for this!

[Kalászi-Krisztián]

Wtfk? Ugyan azok a kèpsorok kapkod a kamera a vágás szöveg nèlkül semmit nem lehet èrteni. Holott állítólag egyszerű mint egy faèk....rásegit gondolom mert kart nem láttam hozzá.

[theebikeguy]

Lmao close to $1, 700 buy the new info in 2024 .in the U.S. only person that would buy that wold be a clueless person that's never owned a ebike, when you can buy a 28-30 mph ebike that gets up to 60 miles starting out at $1, 500.00

[trevormadsen]

I don`t think it can work on foot brake bikes.

[bigglesbiggles]

If its going to be around €1000 as per projected....its way to expensive for what it guess there is a lot pre production advertising hype going off here as so often is the case
