I'm looking at the £500 Saracen Zen as an oversized BMX so I can take daughters round park/bomb around heath for an hour/muck about every now and then. However...I'm 6'6" - I appreciate this is a small bike and I'm not looking for a x-country type fit on it, but will it be TOO small for me? Has anyone seen it in the flesh? Remember, this is a play bike for me, any ideas?
