Safety and security
If you have experience with bike maintenance and the appropriate tools, such as hex wrenches, it shouldn't be too difficult. However, we strongly recommend finding a reliable bike shop nearby—ideally, one with expertise in folding bikes.
The following 2 points are the most important and unique that other bicycles do not have. For more details, please refer iruka owners Manual.
Do not carry the bicycle by the rear wheel when the bicycle is folded. Doing so may lead to injury due to the rear wheel turning and trapping your fingers between the frame and the rear wheel. (iruka is sold with a wheel cover to prevent fingers going through the rear wheel)
Check that the stem and the handle post is inserted to the very bottom and that the cam levers are closed steadily.
iruka's frame strength passed the listed official safety tests conducted by Taiwan Cycling and Health Tech Industry R&D Center.
Frame fatigue test with a vertical force (EN4.8.6)
Impact test (Falling mass) (EN4.8.2)
Impact test (Falling frame) (EN4.8.3)

Tires that exceed 460mm in diameter or 40mm in width may interfere with the main frame when folding. Please check the compatibility in advance when using any tire that exceeds 18-inch x 1.50.
Yes, the upper seat post can be replaced as long as it has a diameter of 27.2 mm. However, if the length exceeds 380 mm, the tip may touch the floor when the bike is folded.
iruka may be customized if each part matches the size of the original parts. However, as all parts of iruka are designed to fold with precision, we don't recommend customizing the drivetrain system or control system. If you do consider customizing your iruka, please seek advice from your retail shop's staff. Below are some possible issues that may arise during customization.
Crank set
A chain ring with a diameter over 250mm or with a cover on the back may interfere with the rear swing arm when folding. Also, when the crank set is changed and the Q factor (the distance between the outside of one crank arm to the outside of the other crank arm) is decreased, the tip of the crank may interfere with the caster when riding, or with the rear end when folding. In general, a front derailleur cannot be installed because there is not enough space.
Bottom bracket
The original bottom bracket is specially designed to use a long axle. If it is changed to a shorter bottom bracket and the Q-factor (the distance between the outside of one crank arm to the outside of the other crank arm) is decreased, the tip of the crank may interfere with the caster when riding, and with the rear end when folding.
Handle bar
A handle with different size and shape might interfere with the frame and/or with the ground surface when folding. Also, when the brake lever and shifter are repositioned significantly different from the original design, it may entangle the wires during folding and unfolding, thereby affecting the bike's braking ability.
Brake A V brake or caliper brake cannot be installed because there is no base for a caliper. A rear disk brake rotor with larger diameter will interfere with the rear end.
Accessories
It is compatible with a saddle with a rail width of 44mm (center distance, allowance ±1mm). It requires an M5 hex wrench for installment.
If the coupler (not included in the product package) can be attached to the saddle, iruCart can be used on bicycles with an approximate wheel radius of 600mm (varies by the saddle height and rear center length).
If the coupler (not included in the product package) can be attached to the saddle, iruCarry can be used on bicycles with a seat post radius of 26-35mm. Please note that when there is not enough space on the seat post, it could cause the back shelf to interfere with the rear, and/or eliminate luggage space.
iruCatch can be attached to a handle post with a diameter of 22-35mm.
We offer iruCanal, detachable mudguards specifically designed for iruka.
It is not in the standard option, however, you can install a kickstand on the left side of the rear using M6 bolts with a 22mm center-to-center distance 22mm.
