带有大开口的折叠框架
iruka最具特色的折刀式车架，优雅地勾勒出双对称弧线。后轮收纳于中央缝隙中，打造出紧凑而优雅的折叠设计。其高刚性结构，顶管（自行车的主梁）上无铰链，实现了骑行性能与便携性的卓越平衡。

伸缩单臂前叉
左侧带有我们原创伸缩折叠机制的粗壮单臂前叉。折叠时，前轮与后轮平行且同轴排列，便于轻松滚动运输。

立式集成后摆臂
当后轮折叠时，Iruka 可以自行站立，因为后框架前端的万向轮充当支架。主框架的连接处安装了弹性体悬挂，能够吸收骑行中的细微振动。

伸缩手柄杆和平把手
我们大幅增强了车把立管底部周围的刚性——这是小轮自行车常见的薄弱点——采用了我们自主研发的伸缩折叠机构。通过安装iruCatch，它瞬间变成了一个包架。高度可调，适应多种位置需求。配备了平直车把，更便于采用进攻型骑行姿势。
配备Shimano高端内变速花鼓Alfine
内置齿轮花鼓具有高耐用性、低维护需求，并且即使在静止状态下也能换挡。对于 Iruka S，我们选择了 Shimano 顶级且绝对可靠的 Alfine 8 速变速系统，确保即使在频繁起停和坡度变化的情况下也能提供异常顺畅的骑行体验。
小型转子盘式制动器
机械碟刹配备140毫米小直径转子，即使在恶劣天气条件下，也能提供出色的制动性能和控制力。
