• Top tube length (TT / A): 20.75 in
• Wheel size: 20 x 2.45 in

The Kink Downside comes with a rear freecoaster, four nylon pegs and four nylon hub guards, so those parts are already included when you put together your street setup. A full 4130 chromoly frame, Relay fork and Foundry bar sit alongside three-piece 165 mm Ridge cranks.

Set up for riding backwards

A freecoaster lets the bike roll backwards without driving the cranks backwards once the mechanism has disengaged. Take time to learn its engagement before trying tricks. Both hubs have sealed cartridge bearings, while the headset and Mid bottom bracket are listed with cartridge bearings.

Adjust your riding position

The Impression Stealth Pivotal saddle allows angle adjustment on the 25.4 mm aluminium post. The 20.75-inch top tube, 12.75-inch chainstays and 9.5-inch bar rise give you clear dimensions to compare with your proportions. The suggested rider height is around 160–180 cm.

Double-wall Mission Mylar rims carry Kink Wake 20 x 2.45-inch tyres. The optional brake set is included: have it fitted and adjusted before riding. The frame has removable brake mounts and is prepared for a gyro installation; check the required parts before making changes.

Safety while riding

Freestyle BMX riding puts high loads through the bike during tricks, jumps and landings. No bike is indestructible: parts can wear out or become damaged. Check the frame, fork, bars, wheels, axles, cranks, pedals, brakes and bolted connections before every ride. Inspect the bike after a hard impact and stop riding if you find looseness, cracks or damage. Have any problem checked and repaired before riding again.

Wear a properly fitted helmet and suitable protective pads. Read our important information before buying and riding a BMX bike for assembly, servicing and riding checks.

Important information about your new bike

• Read the instructions and warranty supplied with the bike before riding.
• The bike is delivered approximately 90% assembled for shipping.
• Before the first ride, fit the pedals, saddle and handlebars, and the front wheel where required. Follow the assembly instructions and check all components.
• Have a professional bike workshop carry out a pre-ride inspection. This is a paid service; keep the receipt as proof for the manufacturer’s warranty and follow the warranty terms supplied with your bike.

The manufacturer’s warranty is separate from your statutory consumer rights. Continue to inspect and service the bike throughout its use.
