Innovative technology packed into a compact size
The ideal form of urban mobility
The true value of a 20-inch electric assist bicycle lies in its compact frame, measuring 1550 x 1200 x 860 mm. Its size allows it to be easily stored in bicycle parking lots in front of train stations during rush hour, yet it can withstand a load of 180 kg. It maintains stability even when carrying a business bag and weekend shopping bags at the same time.
The 20-inch wheels are designed with a low center of gravity, making them more responsive to manhole covers and uneven surfaces. The deep groove tread pattern improves drainage, especially on slippery surfaces after rain.
The heart of a powerful drive system
The true value of the 48V/500W motor
The 500W peak output motor ensures stable operation even on steep 15 degree slopes. In field tests on the pilgrimage route to the Thirty-Three Kannon Temples in Kawagoe, the bike easily cleared an 8 degree gradient section at assist level 3, where conventional electric bicycles would slow down.
Three precisely controlled assist modes:
- ECO mode (power consumption 0.6Wh/km)
- Standard mode (average speed 20km/h)
- Power mode (maximum torque 65Nm)
Battery Management Tips
The 10Ah lithium-ion battery is designed to be charged in 5 hours, assuming nighttime power usage. The 100km cruising range on a full charge easily covers a round trip between Shinagawa and Yokohama Chinatown (approximately 60km).
Riding performance recognized by professional riders
The synergistic effect of Shimano 7-speed
The Shimano True Ibility derailleur, certified by the Alps Technology Institute, seamlessly links electric assist and manual pedaling. In a comparative test conducted on the undulating coastline of the Miura Peninsula, it showed a 23% improvement in climbing efficiency compared to conventional models.
Weight distribution
The weight of the 43kg vehicle precisely controls the load distribution of the front basket (maximum 10kg) and rear carrier (maximum 25kg) . The weight distribution suppresses steering wobble even when fully loaded, and its effectiveness was proven in crowded driving tests in downtown Osaka.
Functional beauty from the user's perspective
New ideas for crime prevention
The double lock system, which combines GPS tracking and a physical key, is standard equipment. In a 24-hour test around Shinjuku Station, it recorded a 99.8% theft prevention rate.
Maintenance-free design
The completely waterproof motor case has achieved zero internal condensation even in the heavy snowfall of Sapporo. The automatic chain lubrication system allows for maintenance-free operation for three months.
