Apollo is Halfords own brand of bikes. This one is two years old now and has been used by my youngest to hone his skills enough for Santa to (possibly) bring him a bigger bike. This one has a 12" frame, v-brakes, upgraded Shimano trigger- style gear shifters from those horrible standard twist grips, 24" wheels and front coil forks, making this an entry level hardtail mountainbike. This bike is as happy on quite demanding forestry roads as it is pottering along the park. This is being sold as my son has outgrown it. Nothing wrong with it at all. Ready to go and provide many more years of biking.
