Gearing question

ANDARIAL · 26 Feb 2022 at 10:35

Noob here so please be gentle

Got a cheapy e-bike with a rear gear with`super low 14-28`printed on the cog
i am finding the gearing too`low?`i.e. i have to pedal like hell to go fast
Would i just need to change out the rear cog/gear to make it so that i would not have to pedal as fast to get the same speed?
or would it involve new chain and deraileur and front cog/pedal?
ignore that is has a motor as it is only the `mechanical` aspect i am asking about

Thanks

14-28 is definitely not low, doubly so for an e-bike. My bike is running 10-30 on an e-bike I'd want at least a 34 on the front with a 10 on the back.

Sorry I said I was a noob.do you mean that my gearing is better than yours?
I can only Pedal at a max speed of 20 mph and want to increase that if possible while pedaling less.....if that makes sense

Even on my 10-42 X 30 I top out on flat or downhills.
Can you change the chainring to something bigger? What does it have fitted at the minute?

my first post
14-28 i think is what you mean??

yeah once i get up to speed with motor,then turn it off i can not get more than 20mph on the flat.My legs are going like the clappers and i can`t pedal any faster
Even not using the motor i can pedal up to 20mph,hard yes but not impossible

Will see if there are any details on the front cogs once it warms up

EDIT counted 42 teeth on the front largest cog.looks like a few are `chipped/smaller`

bike still pedals ok though

Thanks jonny
Changing the rear wheel is a no no as it has the motor inside
The bike is working fine as is,i was just wanting to get a better speed with less revolutions of pedal
Looks like i will not mess with it
Thanks again to all who replied
