I spotted an old "www.allabilitycycling.com/tricyclesbicycles/children/quest-88-kitten-%2812%29.aspx Quest 88 Kitten" trike at Okehampton Recycling Centre ( the porta cabin sales place at the tip) With the bikes and kids ride ons.
The trike is in poor condition, needs new tryes ( maybe wheels). Looks like its to fit a child around 100cm tall. Has a regular saddle with a back support ( unpadded), very upright handle bars, low step over.
As it's at the recycling centre its probably going for just a few quid if any one had the inclination to do it up. New these retail at 500 quid plus. I don't have room for another doer upper bike at present. willing to talk via PM if anyone is interested but out of area.
