If you buy without any inquiry, the default is that represent you can accept a transportation time of up to 365 working days.
Our products will not support refund on the grounds of long transportation time. As long as you purchase, you agree to this clause by default.

Note: because bicycles are large goods, many logistics cannot be carried due to their huge volume or magnets inside the bicycles, but aliexpress logistics system will not update the situation that they cannot be carried, Because there are a lot customers, we can't inform them one by one. so we may change the logistics mode without notifying you instead of using the logistics mode you choose.

R5MechanicalShift version is equipped with 24 speed mechanical transmission, the configuration of this version is the same as R5pro's as shown in the figure below, but the frame is the cyclone frame, making this model very cost-effective.


Additional precautions:
The pedals are composed of left pedal and right pedal, L stands for left and R stands for right. Be sure not to install them on the wrong side. Also, when tightening the pedals, be sure to use all your strength to tighten them. Otherwise, if you ride without tightening the pedals, the screws of pedals and cranks will be damaged and cannot be used. Such damage is not a quality issue and is out of our range of after-sale services.
Except for the pedals, which need to be tightened with maximum force, other screws can be tightened normally. There is no need to tighten them with great force. If excessive force is used, causing the screws damaged, it is not a quality issue and we cannot handle this issue for you.
The tires are not thoroughly inflated at the factory (due to transportation considerations, only a portion of them are inflated at the factory, most of them do not reach the pressure required for riding). After the receiving bikes, tires need to be inflated according to the pressure marked on the outer tire. It cannot be too low or too high. Both too low and too high will cause tires to burst. Burst tires and tire punctures are not quality issues. Inner and outer tires are consumables and are not covered by the warranty. Please be aware of this.
If it is a bike with hydraulic disc brakes, remember not to use the brakes without installing the disc. If you used the brakes without installing the disc, the piston will protrude. At this time, you need to use a flat-blade screwdriver to separate the brake pad from it. This situation is not caused by any quality issue. Please be aware of this.

You can negotiate cooperation with our customer service, and the price can be preferential according to the quantity you want. (Note: if there is only one, then the price will be the link price)

4.When installing the bicycle pedal, you need to use a lot of force to tighten the pedal, otherwise it will slip. Please use the maximum force you can use to tighten the bicycle pedal.
5. About the logistics transportation timeliness: the logistics transportation timeliness depends on the busy and idle of the logistics. As some models of bicycles have magnets, they may not be able to use air transportation, but can only be transported by sea or land. Therefore, please consult the customer service separately for the logistics transportation timeliness, which is not completely subject to the transportation timeliness on the page, but subject to the actual transportation timeliness.
