Why not e-bikes?

There's been some disapproving murmuring within the patchwork of the cyclists in Toronto. People are concerned about e-bikes. There are several points against:
  1. They weigh more and are faster, and thus are more dangerous in a collision.
  2. They take more energy to produce than a normal bike.
  3. The batteries aren't eco-friendly.
  4. People don't use them as power assisted bikes. The pedals come off very easily. Even young able bodied people do this.
Argument 1 is true. The more momentum is involved in a collision, the more damage is likely to be done. It's physics. The only problem is that by this logic, faster heavier riders are as much, or more, of a safety concern as someone on an e-bike.

For example, I weigh almost 200 pounds, and my bike another 25. I was going 48 km/h on College yesterday. If I'd hit someone at that speed, I would have been a lot more likely to kill or injure than a 150 pound person on a 100 pound e-bike going 32 km/h.

By the same argument as 1 and 2 use, it could be argued that recumbent bikes and velocars should not be legal: they are both faster and weigh more than a normal wedgie bike. Without legislating against heavier riders and certain kinds of bikes, it would be hard to make a law against e-bikes on the grounds of argument 1.

Arguments 2 and 3 are both true, but not if you compare to alternatives. The alternatives to e-bikes are cars, buses, street cars and subways. Each of these requires batteries, and each takes more raw material to produce than an e-bike. It would be interesting to compare an e-bikes footprint to the shared footprints of various modes of public transit per person, but it's pretty obvious that an e-bike is better for the environment than a car.

Argument 4 is surely true. I've seen people with no pedals using e-bikes in bike lanes. But there's no law that says a bike has to be operated with pedals on. It takes less than a minute to take the pedals off any bike.

There are a lot of people in society who want to get around town in something less resource intensive than a car, but don't want to bike for whatever reason. An e-bike is the obvious solution for these folks.

The arguments that e-bike opponents make are all true, but they don't form grounds for banning e-bikes, either from bike lanes or in general. I understand not liking e-bikes for aesthetic or environmental reasons, but to suggest that they don't belong on our roads is wrong.

Good post. Some people would ride a bike if it didn't create so much sweat. For them, an e-bike is a solution that gets them on a bike, but doesn't require breaking the sweat threshold.

I would prefer that people use human-power when feasible, but I support e-bikes if people would choose cars instead.

I totally agree with your last sentence Mark. I see e-bikes as a decent compromise.

I was wrong with my weight estimate. E-bikes can be quite hefty. Someone on i bike t.o. posted a link to one that weighs 185 pounds.

An angle I hadn't considered here is tandems. They're faster and easily heavier than e-bikes. If you have 2 180 pound rides on a 50 pound bike, it will definitely weigh more than an e-bike.
