Spinning out - which cassette ?

[Chess]

Hi all.
Enjoying my ebike, but I need to change my rear cassette as I'm spinning out on the flats/slight downhills ( no e assist obviously )
It's currently an 11x34.
Am I right in thinking an 11x32 would better solve my problem ? or have I got it totally wrong ?
Advice and recommendations appreciated.
Cheers,
Dale.

wrong - you'd want a larger chain ring. (or a smaller cassette, but less than 11tooth is impractical)

Or peddle faster! What rpm are you describing as 'spinning out'?

Are you using all of your gears? what chain-ring size are you on? Spinning out on 48/11 is already quite fast! And if so I suspect you'd get on better without the weight of the ebike!

If you're already in the big ring at the front and the 11 sprocket at the back, then no. Putting a 32 at the back will make it easier up hills; it will lower the gearing. What you need is a larger chain ring.

No, it's the 11t that's in use when you're spinning out, not the 32t.

Possible solutions:

a) bigger chainwheel
b) learn to pedal faster
c) learn to enjoy freewheeling

Er, no it won't.

So who's right here ?
Can't easily change the front single chainring as the sensor is built into it.
So my easiest / cheapest option is to go for a different cassette.
But I'm not sure which one - teeth number wise ?
Thanks in advance and sorry if I opened a can of worms.

Blimey, I dream of spinning out on any cog when on the big chainring . Mind those Gatsos lol

I'm now confused at what you want.

What bike do you have?

11t on the rear is currently as big as conventional cassettes go, so you already have the tallest gear available. If you could tell us what you have on the front, that would be helpful.

As a general observation though, unless your only objective is to go as fast as possible downhill, then a better option would be simply to tuck in and freewheel.

Picture of the front chainring ?

O.K. Thanks guys. Think I'll stick with what I have as you suggest and enjoy the freewheel/ride. It was just a thought but I can live with it. Maybe I need to learn more about mechanics/gearing ect.
I do love this forum, learning all the time. !
Cheers.

Er, no it won't.

Why not? Are electric bikes different?

Pedal faster.

Suntour 38t - 175mm crank arms - single chainring.
Carrera Vulcan E

Good intro to gear ratios here: https://www.britishcycling.org.uk/knowledge/bike-kit/article/izn20130703-Understanding-gears-0

Cos it's already 11-34. So putting a 32 on the back would raise the bottom gear, not lower it.
