Compatibility, Size and Fit
Check the 17" frame size, 26" wheel size and stated rider height range before choosing an offer. The bike also uses a standard 26 x 1.95 inner tube with a 60 mm Schrader valve, which matters if you plan to replace the tube later.
What Is Included
The bike includes the main bicycle configuration described above, with alloy frame, 21-speed gearing, disc brake, front suspension fork, kickstand and Shimano parts. A bell is not included.
What Else You May Need
You will need to complete the remaining assembly and check the brakes, gears and fixings before riding. The product text also says a local bike shop may be needed for assistance with assembly or adjustment.
Important Limitations
This bicycle is stated for normal use only and is not intended for competition, stunt riding or ramp jumping. The front wheel fitting method is described as a quick release arrangement, so the correct front-wheel setup matters.
Before You Decide
Confirm the 17" frame, 26" wheels and stated height range match the rider. Check whether you are happy with an 85% assembled bike and whether you need help with final fitting and adjustment. If you need a bell, remember that it is not included.
