You can't go wrong with the Trek Marlin 7 - a popular entry-level hardtail mountain bike. Size small aluminum frame with a curved top tube for better stand over clearance. The bike has had a full overhaul, all new wheels and tyres, new pedals, new seat, new hand grips, new gears - new everything. Almost a new bike! I can include a soft gel seat cover if you wish. The crank length is 170mm and the wheel size is 27.5". Only ridden once since overhaul. Getting a bargain here. Selling as upgraded to an electric bike. Feel free to come and view. Located in Parklands, Christchurch. Prefer the buyer to pick up, but I can deliver to you in the Christchurch area if needed.
