I am very new to the sport and my 11 year old daughter has shown an interest in getting on a bike  

She is 6 Stone and 1.43 Meters and I am looking to spend up top £1,500 can anyone give me some advice what i should be looking for.

Thanks

 

I didn't know about the electrics at the time or I might have picked up an OSET for my daughter and would say look into them if its trials riding around the yard and events, however if you want more range and gas powered...

When my Daughter was 11 and around the same size I was able to get her a full sized Beta 80 that worked well over all.  It was a bit tall so a consideration to help might be to get a set of the small wheels from the smaller Beta 80 and have spacers created to fit them to the full sized 80. 

FYI: I know the smaller 80 wheels can be adapted with spacers I just don't know if you need to change anything with the brake disks or not. 

As for gearing the slow speed of the Beta is great!...
