Assembly Instructions – 20/24″ Bikes

Congratulations on your purchase of a brand new Forth Bike! This assembly manual is designed to help you assemble your bike safely and correctly. Please read all the instructions carefully before beginning the assembly process.

Tools Required:

  • Allen wrenches (metric and/or imperial sizes)
  • Open-end wrenches (metric and/or imperial sizes)
  • Phillips head screwdriver
  • Flathead screwdriver
  • Pedal wrench (optional)

Assembly Steps:

  1. Remove all the packaging materials and inspect the bike to make sure all the parts are included and undamaged. If any parts are missing or damaged, please contact us immediately.
  2. Install the handlebar onto the fork stem. Tighten the stem bolt securely, but be careful not to overtighten. Align the handlebar to the front wheel, and tighten the screws on both sides of the stem.
  3. Install the front wheel onto the fork dropouts. Make sure the quick-release lever is in the open position before inserting the wheel. Tighten the quick-release skewer until it’s snug, and then close the lever.
  4. Install the pedals onto the cranks. The left pedal has a left-hand thread and must be screwed in counter clock-wise. The right pedal has a right-hand thread and must be screwed in clockwise. Use a pedal wrench if available.
  5. Install the saddle onto the seatpost. Adjust the saddle height and tilt to your preference, and then tighten the seat clamp bolt securely.
  6. Adjust the brakes. Adjust the caliper evenly so the pads do not rub on the rotor. Test the brakes before riding the bike.
  7. Adjust the gears. Shift through all the gears and adjust the cable tension and limit screws as necessary. Test the gears before riding the bike.
  8. Inflate the tires. Check the recommended tire pressure, which is usually printed on the sidewall of the tire. Use a bike pump to inflate the tires to the proper pressure.
  9. Setup the air fork (if equipped). Check the recommended fork pressure, which is usually printed on the back of the fork. Use a shock pump to adjust the air fork to the proper pressure.
    NOTE: fork air pressure will vary, depending on terrain and riding style.
  10. Test ride the bike. Before going for a longer ride, test the bike in a safe area to make sure everything is working properly. Make any necessary adjustments before riding on the road or trails.

Congratulations! Your bicycle is now assembled and ready to ride. Always wear a helmet, obey
all traffic laws and regulations, and respect the trails. Enjoy your new bike!
