There are ebikes with the Shimano Alfine 11 which does have better ratios then the seven and eight speeds.

I had one.

Connecting the cable was simple, but only just possible with fingers.

To be sure, you would need to carry a small pair of pin nose pliers.
So shimano 11 is also a pain to reconnect but not as big a pain as shimano 8?

I the spec they mention both pinion and enviolo
Thanks?
 
The pinion in the spec of that bike is a heading, it's how the Germans describe a sprocket.

That bike has an Enviolo/NuVinci pinion - sprocket.

A Rohloff bike described in those terms would have Rohloff pinion, or a Gates one if it had a belt.

The Pinion (capital P) gearbox is a bottom bracket gearbox made by a company called Pinion.

It can be fitted to pushbikes or ebikes.

I've not done an eight for a while, and they may vary a little bit.

Disconnecting an 11 is a bit of a pain at the roadside, and may not be possible with your fingers, depending on their strength and dexterity.

Most ebikes have puncture resistant tyres, and there's always the option of a Gaadi snake tube which you could fit without taking off the wheel.

Bear in mind you would probably want to remove the old tube completely which would mean slicing it, so you would have to carry a craft knife or similar.

The ratios are almost identical between 8sp and 11sp Shimano hubs. Its only the last 3 gears which give a higher top speed
Yes, I should have said the 11 has a wider ratio spread.

Worth having in my view, although plenty of riders manage happily on an eight speed.

I must confess I have an eight speed and it works fine for me, but then I dont have many hills
The Alfine 11 is better suited to flats, so you can take advantage of gears 9 to 11 for higher top speed.

You will have the same lowest gearing on both Alfine 8 or 11

If I was thinking of building a new ebike, wanted everything, power, big tyres, racks and lights. I would look for a single speed or 11 speed Shimano hub donor bike. I would then opt for Bafang BBSHD crank drive.

You could have a super dooper for less than £2k

Its all well and good these top end bikes but £6k is way too much.

I would be happy with 8 speed if wasn't such a pain to put back on. Although I found the gap between gears very annoying. Top speed is irrelevant as I only use it to pull trailers so it is dodgy to cycle to fast (brake to hard and trailer will overtake. The enviolo looks like an obvious way of dealing with the gap between gears. I have used the snake before I think something went wrong with it. Although I can't think what. I nearly always have a pen knife with me. Thanks all
