Hey mate try www.tartybikes.com they will have everything to make your bike perfect but if you've got £350 to spend why dont you get a second hand bike? BUT i do think that you may be beter if you get a mod (20") instead of a stock (26") because i tried a stock to begin with ( I was 14 at 5 foot 2") and didn't progress ATALL!! in 4 months not even 5 rear wheel hops But 1 month ago i got a mod (20") and can rear wheel hop 25 easy,pedal kick, drop off and now learning to pedal kick higher but all that in 1 month but im 15 now at 5foot 6" Also if you go on tartybikes on the video gide to buying a bike adam says minium hight for a stock (26") is bout 5foot 6" so you will probably struggle with your phase but if you go mod i highly sugges an onza T-pro or something like that try ebay good luck mate.
