HDC-5E Cargo hydraulic disc brakes has new upgraded parking switch. Instead only one position, this new switch provide total 5 parking positions which help people to park the cargo more easily. Rider just need light finger force to lock or release the parking switch. The key components of the switch is out of MIM technology with stainless.

The quad piston caliper is out of 6061T6 aluminum one body forged technology which provide extremly stiffness and robust brake performance. Brake pad is out of sinter metal material which result in great lifecycle.

Easy, Safety, Robust

This brake is special design for flat bar road bike with internal hose routing. The brake lever body and blade are out of aluminum forging technology. The floating banjor connector on the brake lever helps hose toward handle bar and can go inside frame more easily.

The new caliper has much smaller size and has an option to equip cooling fin brake pad.

G-series cooling rotors are special designed for high performance disc brake version bikes.
G1: Standard rotor, 51 seconds cooling down from 300 degree to 30 degree
G2: With additional riveted cooling fins, 16 seconds cooling down from 300 degree to 30 degree
G3: With additional riveted cooling fins and center aluminum spider, 11 seconds cooling down from 300 degree to 30 degree

This automatic internal 3 speed hub is a new innovation to the bicycle industry. It helps people to ride bike more easy and fun. It is a purely speed driven automatic shifting gear hub with double clutch system inside. Without shifting cable and shifting lever, make the bike more clean and maintenance free.

The gear hub has a gear ration of 1:1.36:1.85 which covers majority of city bike gear range . Key components are made by cold forging, CNC, carburizing technoloy and provide great performance and lifecycle. The hub equiped with high precised sealed ball bearings with IPX7 performance.

WIth 26inch wheel, it has shifting points at speed 12km/h to middle gear and 18km/h to top gear.

There is an option to has built in hall sensor speed measurement with 6 signal per round. This will provide more accurate speed measuring when riding.

There are toal 5 specs at this moments:
- 135 OLD hydraulic disc brake version, M12 axle, snap on sprocket /belt interface.
- 135 OLD hydraulic disc brake verison, M12 axle, 9 teeth powerspline sprocket /belt interface.
- 149 OLD electric drum brake version, M12 axle, snap on sprocket /belt interface.
