How to Build Your Own Single Speed Mountain Bike: A Step-By-Step Guide
To make a single speed mountain bike, start by removing all the gears and shifters from your existing mountain bike. Next, purchase a single speed conversion kit, which includes a single cog or freewheel and a chain tensioner. Install the single cog or freewheel onto the rear hub, then attach the chain tensioner to the rear derailleur hanger. Finally, adjust the chain to the correct tension and test ride the bike to make sure everything is working properly.
