Rubbee Electrifies an Ordinary Bicycle in Less Than 1 Minute (w/video)

AUG 9 2013 BY ERIC LOVEDAY 12

Say you own a conventional bicycle.  Maybe it’s a bit dated and possibly too slow for your tastes.  You could “shape up” to quicken its pace.  You could upgrade to the latest carbon fiber one out there.  Or you could electrify it with Rubbee.Rubbee-electric-bike-conversion-1-e1374171158540

Rubbee is the dream of a London-Based company who’s looking for funding via Kickstarter.

Rubbee, to us, is revolutionary.  In less than one minute, Rubbee can electrify almost any bicycle out there.  You simply clamp Rubbee on the seat tube and then make sure that its polyurethane cast friction wheel makes contact with the bike’s back tire.  It weighs only 14 pounds, but provides up to 15 miles of range at speeds of up to 15 mph (both specs are without pedaling done by the cyclist).

The battery pack is housed within the system and can supposedly be charger daily for five years without losing capacity.  A full recharge takes around 2 hours.

The entire unit will retail for $1,073, which isn’t cheap, but neither is your average electric bicycle.  The true breakthrough with Rubbee is that it can be installed and removed whenever.  That means that you don’t always have to lug around 14 extra pounds on your bike.  Just install it when needed.  It only takes a minute!

I don’t like friction based system like this. They are bound to be very inefficient.

Pretty sure electric bicycle riders aren’t that efficient either.

It might not feel idea but I actually think it can be quite good. If you think about it, it’s not much different from the contact with the road and coupling to a large wheel has the significant advantage that it fits better with high motor rpm which allows the use of a very small motor. Thus cheap.
It also allows all the parts to be in one unit.

It’s of course better if the bike was built electric to begin with but if you have to retrofit then I think this approach can be quite good. Maybe best of all.
The only problem here is the missing cargo rack and fender. They need solutions for that.

I believe this lame product. It’s too heavy, too inefficient, too expensive.

Their engineers need to cut the weight in half along with the price and use direct drive instead of friction. Geez.

See what I did there? 😉

I saw what you did there Dave. Lol!

It’s not exactly subtle 🙂
It’s not too heavy and it’s probably quite efficient but it is too expensive. By quite some margin.
The price obviously can’t be as much as an entire electric bike.

Hey Eric – Hey Kickstarter,

It’s been done already! http://www.goped.com/Products/GoBike/default.asp

And this American-made one has a rack on top for portaging your stuff!

Sweet!!!

Can’t buy it anymore as far as I can tell.

That price is so specific. I couldn’t find any retail price at all. All I know is that for £1000, the donator can receive a limited pre-production version as a “thank you”. It’s like how Google sent out $1500 Google Glasses to a few thousand testers, or how the pre-production UOYA consoles became more expensive and less, of say quality and compatibility.
My guesses are that it’ll be cheaper when it comes to market.

Fail by design.

It can only used on bikes with uncovered wheels, makes you very dirty when driving.

Dumb question – how do you stop?
