Rjp thanks so much ill take a look tp see how the secure the gear cassette is and/or if it has any
Wobble/play to
It

Thanks all for your replies, ill give the adjustment another go.  My issue is strange its like it skips gear teeth when i put presurre on in the higher gears

Hi all,

Just got my new rad rover and furst ebike, unfortunatly off to a bad start.

As with most users im predominetly driving the bike in gears 5-7.  Gears 6-7 are constantly slipping.  I tried a barrel adjustment on the derailer, but it hasnt helped.  I took the bike to a cycle shop, and the fella said another user came in with sane problem.  He said the gear cassette is cheap and unbranded, and therefore jot reliable, a free wheel would have been better.  That aside, has anyone encountered this before the top gears slipping, do u know what the fix might be?

Hope you can help, thank you all for taking the time to read.
