Why do the majority of people on an ebike ride at a fairly low cadence?

There are (at least) two reasons. First, most (but not all) E-bikes use a control system that multiplies the amount of force or torque that you put into the pedals or cranks. Since power is the ...

Why aren't electric bikes mainstream?

Why do the majority of people on an ebike ride at a fairly low cadence?

In general studies have indicated that trained cyclists use pedaling frequencies higher than 90 rpm whereas untrained cyclists prefer frequencies around 60 rpm. I suspect the majority of e-bikers you ...

Why are regenerative brakes uncommon on e-bikes?

There are several reasons for regenerative brakes not being common on bicycles unlike in electric cars: Electric bicycles have very poor acceleration, and the rider produces about half of the ...

I would like a one-mile-range e-bike: why aren't there any?

I think the ultimate issue boils down to a lack of demand for such a short-ranged product. Looking broadly at the entire electric vehicle market, range anxiety is fairly common. Most people are ...

Why do e-bikes need dedicated tires?

They don't need them but they are good to have. I have an e-bike that I use as a daily commuter. Here are my thoughts: E-bikes are heavier than regular bikes and put considerably more power out at ...

Cycling to work - 30 mile return

Even with an e-bike going to 150 miles a week is a big jump. Likely you just need to have a few rest days to allow your body to adapt and recover. 3 weeks is the range in where you start run into ...

Why do the majority of people on an ebike ride at a fairly low cadence?

Personally it's because I'm using my ebike to get to work, wearing work clothes (which restrict my pedalling) and not wanting to get too sweaty. If I were just out for a ride I'd pedal faster.

How many watts are lost when pedalling on Bosch e-bike without a motor/electricity?

In theory - none because the motor has a freewheeling clutch that is completely disconnected when it is not providing assistance. That is when you're travelling over 25 km/h (location-dependent) or ...

Why are regenerative brakes uncommon on e-bikes?

Short answer: it's not worthwhile. Most bicycling energy goes toward overcoming wind resistance, especially for casual riders. That energy is lost, with no chance for regeneration. Liberty Trike ...

The stock brakes on many e-bikes may be inadequate. What changes would make them adequate, and at what cost?

The problem I see constantly is lack of maintenance. It's very common for ebikes of all varieties to come into the shop I work at with brakes that the user has treated essentially as an automotive ...

Cycling to work - 30 mile return

I moved house in August, and have had a 26 km commute so roughly similar. Mine's got 50 metres drop on the way to work, so mostly flat. In my experience, you're in the distance where comfort becomes ...

Why aren't electric bikes mainstream?

Cost is the overarching reason. Not only buying (and re-buying after theft!) but also maintaining. I can happily leave a cheap bike in the rain for a year; at worst I'll buy a new chain (€10) that I ...

Why do the majority of people on an ebike ride at a fairly low cadence?

For me, as an occassional ebike rider, it feels I get kind of better connection to the bike when pedaling at lower cadence, but higher force. Because the electric assist otherwise reduces the needed ...

Are electric bike speed limitations set in stone?

The limit is set by law depending on the country. There's nothing to prevent you from going faster if you can pedal harder. The limiter just cuts off the electric assistance above 25km/h, so you'll ...

Apart from going the high-tech route of a front suspension with lock-out, you can also try to get wider tires. The slow-down of wide tires is not that big, but they naturally even out high-frequency ...

Exceeding speed limit with Ebike, is battery affected?

Actually, when you are running the motor near the top of the speed limiter, it's the happiest and most likely drawing the least current. If you had a CycleAnalyst or other amp gauge, you'd see it ...
