"Today's electric powered bike has pedals because they created a legal loophole that allowed manufacturers to successfully lobby that they were power-assisted bicycles, not motorbikes, and thus dodge complicated and expensive safety regulations, as well as licensing and insurance requirements that motorcycles and motor scooters must comply with for highway use."

"The deception isthat bicycle makers who aren't making motors are in the motorbike business. History suggests otherwise - that bicycle makers, most of which are staffed by ex competitors, will wage a technology war against each other, both on the racetracks and in their boardrooms, and in doing so, will win the battle for the motor makers. It won't take long for customers to figure out that they are not paying to pedal - and that spending money on speed, power, and battery duration is far more beneficial than ponying up for a carbon frame and a fancy cockpit. When that happens, bike makers will have nothing valuable to sell them that couldn't be produced elsewhere for less."

 

Massive statement that.

What I don't understand - if they're going all "motor in the bottom bracket" - why do those bikes still have traditional gearing. Why does the motor incorporate a gear box. Kind of like Greg Minnaar's Honda setup. Pinion have been doing a decent job of miniaturising their gear box.

these guys also use a gear box, electric motor ...........

Pinion's solution is a separate motor in the hub, which seems like a step backwards:

Yes but the reality is that the amount of power these things produce (50W to 200W) is not enough for effective travel uphill unless the rider assists. Most will not feed electric power to the drivetrain unless the rider is also actively turning the cranks - although it won't be much of a challenge to bypass that limitation.

 

In time I guess better batteries and motors will appear.....

 

If we will have to share trails or even race courses with these things then that power limitation is important. A set of standards is required because at present there doesn't seem to be any. Its the wild west.

I've been riding around with the Specialized Turbo S the last couple of days. As a commuter it's brilliant. Would I ride an electric on a trail? No. The suffering is part of the fun of cycling.
