If your still looking for a bike, i would say the best 20" bikes for beginners are, onza t-bird, onza t-vee,yaabaa 449, shogun gimp or just have a look on eboy for second hand bike. I Brought a onza t-bird magura edtion for just £200 for. but look around and see what you can find but anything under £300 is a bargin and is prity mich enough for a starter bike. ryan member of JJR
