Review on 🚲 6-Speed Bicycle Shift Lever - Right Hand Thumb Shifter SL-TX30-6R for Folding Bikes, Mountain Biking, and City Cycling by Adam Cummings

My child was disappointed with the shift knob on a brand new bike and it was very difficult to turn. It's okay for adults, but difficult for children. Super easy installation and works like a charm. My child was able to shift from 1 to 6 and back to 1 with no problem. Before disengaging the existing gear knob, make sure it is in the lowest gear (smallest gear size or maximum number on the knob (6 or 7)). When setting the pressure switch, make sure it is also under the same number. All you have to do is tighten the cable until it is taut and tighten the nut holding the cable. Do not cut the cable yet. Lift the rear end of the wheel and spin the bike by hand. Use the thumb switch to upshift one at a time. Rotate the handle again to ensure the chain moves to the selected gear before changing gears. Repeat the process until you get to 1. If the gears aren't shifting properly, you may need to adjust the high and low shift settings. It has many videos on YouTube. Very easy to install.
