Not really worth it in my opinion...looks like a monty alp 219 with a fixed 22 tooth cog up front and a freewheel on the back ,Not really reliable.
chuck it on ebay ,save up some money and get a decent second hand bike thats already kitted out and up to the job.
Well you could upgrade the cranks with front freewheel and a fixed cog on the back ,new bar ,new stem ,Some avid sd7' v brakes with decent pads ,and it would be pretty deceee
Sell me them tyres
