A good mountain bike

Description:

I am looking for a good mountain bike, preferably a Whyte or other good brand since they are good quality. Looking for a light mtb, good for hills and London bike rides and big jumps. I am willing to swap my specialised alliez sport for a mtb anyone offers me, or around £200-£250. I can include a Spare wheel for the bike. If someone offers me a good mtb, I can trade them the bike and some money. If interested in the bike, please contact me. I can send pictures to people interested and more spec on the bike. The bike has a medium frame and 700c wheels. Good for someone who is getting out of mountain biking and into road biking.
Thanks for looking.
