Rockrider e-st900 - speed sensor question

[Splodge]

Hi bought the rockrider in July and can say the bike as done everything I’ve asked of it and I’ve asked a lot.
Last week I kept getting a error ( speed signal 81 ) and the Moyer would cut out so off to decathlon and no problems they fitted a new speed sensor, back home and changed got on the bike and in less than a mile it was holding back and then surging so back to decathlon who said they would look at it the next day. Sure enough the next day I got a text my bike was fixed so off I popped sure enough the bike works fine but when I come to a stop on the bike the display still reads x amount of mph for 3 to 4 seconds before going back to zero which I never noticed before, so could someone see if there’s is the same
Thanks Splodge

I know this post is a bit old but I was curious if you ended up doing any mods? I’ve had mine for a week or so and thinking a bit more speed would be nice – cheers

No not messed with it while under warranty mate

Have a look at @BeBiker posts on the est900. He’s done quite a few mods.
