Convert a Bike by adding a pair of pedals!
I just found out about this, and I think it’s a brilliant invention. Wish I’d thought of it. See the image below : a pair of pedals that ARE an electric bike. The pedals turn the bike into an electric bike. but how?
Have you ever had a pedal jam and not rotate? It’s annoying. As the crank goes around the stuck pedal rotates under your foot and makes it hard to pedal. These pedals have the opposite effect. The motor inside makes them rotate with respect to the crank but your foot keeps them horizontal, and that forces the crank to rotate.
Obviously there are limitations in getting motor plus battery into something as small as a pedal. If you have seen my post on the Vivax Assist motor that has 200 Watt motor within a seat tube you know that getting a motor small enough is not such a problem, but getting a battery small enough, and useful enough is.
Therefore these will not replace a 250 Watt conversion nor go as far as a typical 36V 10AH battery but will give some “help”…an extra one third of your power and for 15km they say.
The main benefit of these pedals is that they can easily be added to a bike, any bike, and taken off and put on another bike, and require no battery or wiring. This is similar in effect (but less clever or powerful) to the all-in-one wheel conversions such as FlyKly wheel that I mention in another post here.
Another advantage is that the pedals are in effect a “central motor” because they work on the chain and through the bike’s gears as a central motor does.
The on/off happens by flipping the pedals over. So they are alway on, or always off. There not being a throttle or PAS is a disadvantage.
