C21 electric leisure tricycle丨Full-scenario power matrix, hard-core configuration defines a new travel benchmark

Dual power platform: precise balance of power and efficiency

Motor system: dual-specification power core, adaptable to multiple scenarios

•48V/60V-500W30H economic motor:

Adopting 30H high-magnetic steel rare earth material, no-load speed of 500 rpm, energy efficiency ratio of 8.3W·h/km, suitable for light-load travel on flat roads in cities, endurance loss rate as low as 8%, especially suitable for high-frequency and low-intensity use scenarios such as elderly walking and short-distance shopping.

•60V/72V-650W35H powerful motor:

Upgraded 35H magnetic steel material, peak torque increased by 28%, can easily cope with 25° slope, 35H magnetic steel anti-demagnetization ability increased by 30%, long-term load-carrying power attenuation rate ≤10%, adapted to complex road conditions such as carrying people and goods, climbing in urban and rural areas.

Controller advantages: 12-tube sine wave intelligent control

Equipped with a 12-tube sine wave controller, it supports dynamic motor power distribution and can maintain current output accuracy of ±0.5A in a 48V-72V wide voltage system. With over-temperature protection (automatic power reduction at 75℃) and under-voltage protection functions, the motor life is extended by 25%.

Battery configuration: Four specifications of endurance solutions, covering all scene needs

•48V32AH large-capacity battery:

The endurance range is 50-60 kilometers (economic mode), suitable for high-frequency short-distance travel within 10 kilometers per day, the BMS battery management system monitors voltage/temperature in real time, and the cycle life exceeds 800 times, which is suitable for daily travel for elderly users.

•60V32AH long-endurance battery:

The voltage is increased by 25%, the endurance is up to 65-75 kilometers, and it supports long-distance outings for 2-3 people. It is equipped with intelligent charging management as standard, and the household 220V power supply is fully charged in 8 hours, which is suitable for family weekend cross-regional travel.

•60V20AH standard battery:

Balanced endurance and weight, endurance of about 50-55 kilometers, body weight reduced by 10kg, easier to push, suitable for single-person commuting or light load scenarios such as shopping for groceries and picking up children.

•72V20AH high-energy battery:

The power response speed of the 72V high-voltage system is increased by 15%, the motor power output is more stable when climbing, the endurance is 55-60 kilometers, and it supports 3-hour fast charging (charged to 80%), which is suitable for frequent climbing sections in urban and rural areas.

Body design: 2030mm golden wheelbase, both comfort and passability

•Body specifications: 203010001120MM size, wheelbase 1400MM, standard three-person seat cushion (width 900MM), leg space of 650MM, adults are not cramped; ground clearance 150MM, no pressure to pass speed bumps and small steps, passability is better than 90% of similar models.

•31-tube hydraulic front fork:

Built-in two-way damping valve, road vibration filtering efficiency reaches 65%, with rear spring shock absorption, vertical bump amplitude ≤2.5cm when riding, waist fatigue is reduced by 45% after long-term riding, suitable for comfortable travel for elderly users.

Safety configuration: full-wrapped braking + explosion-proof tire technology

•Brake system: front and rear drum brakes, front 110mm + rear 130mm brake discs, braking distance ≤2.3 meters at 20km/h, equipped with automatic gap compensation function to avoid braking force attenuation after long-term use, and hand-foot linkage design takes into account the operating habits of different users.

•Tire advantages: 3.00-10 tubeless steel wire tire, tread with aramid anti-puncture layer, puncture resistance increased by 70%, tire pressure maintenance time extended to 6 months without inflation, with aluminum alloy wheels, lightweight design reduces energy consumption by 8%.

Analysis of the difference in selling points of models

48V32AH elderly mobility model

•Key words: safe and low speed, light and easy to control, long-life battery

•Scenario adaptation: for users over 60 years old to travel in the community, the maximum speed limit is 20km/h, the body weighs only 90kg, easy to push, standard voice prompt system and reflective strips, safer for night travel.

60V32AH family outing model

•Key words: three-person ride, long battery life, comfortable suspension

•Scenario adaptation: family weekend suburban riding (can carry 2 adults and 1 child), the rear storage box has a volume of 60L, standard awning interface and USB charging port, hydraulic front fork filters bumps, suitable for traveling with the elderly and children

60V20AH lightweight commuter model

•Core keywords: light and flexible, short-distance high efficiency, economical and energy-saving

•Scenario adaptation: office workers commute within 5 kilometers, the body is narrow 1000MM, it is easy to shuttle through alleys and subway entrances, the 500W motor has low energy consumption, and the average daily use cost is less than 1 yuan.

72V20AH urban and rural power model

•Core keywords: strong climbing, load-bearing durability, fast charging technology

•Scenario adaptation: urban and rural commuting (frequent ups and downs), small cargo transportation (vehicle load-bearing 200kg), 650W motor + 72V system climbing torque increased by 35%, steep slope start without slipping, suitable for middle-aged and young load-bearing users.

C21 uses "four-specification battery + dual-power motor" to build a full-scenario power matrix, from safe commuting for the elderly to urban and rural load-bearing transportation, from family outings to single commuting, each configuration accurately matches user needs. The hydraulic suspension and run-flat tire design take into account both comfort and safety, and is an all-around solution for urban micro-mobility and urban and rural commuting.
