Safety and security
自転車のメンテナンスの経験と六角レンチなどの適切な工具をお持ちであれば、それほど難しくはありません。しかし、できうるならば信頼できる自転車店を見つけておくことを強くお勧めします。特に折りたたみ自転車に十分な知見のあるお店ならなお良いでしょう。
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 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
レール幅44mm（芯間距離 ±1mm程度の許容あり）のサドルに対応しています。取り付けにはM5アーレンキーが必要です。
別売りのカプラーをサドルに取り付ければ、概ね車輪径600mm以内（サドル高・リアセンター長によって変動します）の自転車で使用可能です。
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.
