There are three types of solid, inflatable tube and tubeless inflatable tube. Solid type in the flat walk faster and not easy to blast, easy to push, but on the uneven road vibration, and stuck in the same width of the ditch with the tire is not easy to pull out, wear resistance and easy maintenance; The inflatable inner tube is difficult to push, but also easy to puncture, good elasticity and shock absorption effect; Tubeless inflatable type because tubeless will not puncture, and the inside also inflatable, comfortable to sit up, but more difficult to push than solid.
The brake
The large wheel should have brakes in each round. Of course, if the hemiplegic can only use one hand, it has to use the single hand brake, but it can also be installed with the extension rod to manipulate the brake on both sides.
There are two kinds of brakes: ⑴ concave brake (hand brake/holding brake). This brake is safe and reliable, but laborious. After adjustment, it can also brake on the slope. If it is adjusted to level 1, it can not brake on the flat ground. ⑵ elbow joint brake. Using the lever principle, through several joints and then braking, its mechanical advantages are stronger than the concave brake, but the failure is faster. In order to increase the braking force of the patient, the extension rod is often added to the brake, but this rod is easy to damage, if not regularly checked will affect the safety.
In addition, the rear push handle can be equipped with line brake (nursing brake).
