Ryusho Co., Ltd. (Brand: Sun Emperor, Headquartered in Nagoya, Aichi) will unveil the practical specifications of the 'LBIRD,' a 4-wheel specified small motorized bicycle scheduled to launch on Makuake on April 27. The design focuses on daily utility for grocery shopping and short-distance travel, featuring a maximum payload of 120 kg, gradeability of up to 33%, and standard front and rear disc brakes.
### 120kg Maximum Payload: Carry Your Belongings With Ease
The LBIRD is designed with a 120kg payload capacity, ensuring sufficient performance for carrying groceries and daily necessities. It provides peace of mind in life scenes where luggage tends to increase, such as bulk buying at supermarkets or weekend shopping.
### 33% Gradeability: For Hilly Residential Areas
Many regional cities and residential areas have hilly environments. The LBIRD is equipped with uphill performance for inclines up to approximately 33%, reducing anxiety during daily movement on slopes. Stable driving force from two electric motors (rated output 0.25kW x 2, total 0.50kW) reduces the stress of stopping or losing speed mid-slope.
### Front and Rear Disc Brakes: Reliability in Stopping
Stopping performance is as vital as driving performance for mobility. The LBIRD comes standard with disc brakes on both front and rear, ensuring braking power regardless of weather or road conditions. The company believes that being able to stop safely is synonymous with being able to ride with peace of mind.
### Design Philosophy: Utility Derived from Real-World Scenes
The design is focused on real-world scenarios such as 'going shopping,' 'climbing hills,' and 'riding on rainy days,' rather than just catalog specifications. It aims to be a 'truly usable 4-wheeler in daily life' for active seniors, those considering surrendering their driver's licenses, or those looking for short-distance transport without a license.
