As a professional bikes OEM manufacturer with 15+ years of experience in adaptive mobility solutions, we specialize in producing adult tricycles tailored for senior centers. Our engineering team prioritizes ergonomic design, stability, and accessibility to meet the unique needs of elderly users. Below are three core comfort-focused features integrated into our products:
1. Adjustable Ergonomic Frame Geometry
Our tricycles utilize a modular aluminum alloy frame system that allows customization of seat height (range: 75-95cm), handlebar angle (±20° rotation), and footrest positioning. This adaptability accommodates varying body proportions and mobility limitations common in seniors. The 24-inch rear wheels with low-step-through design reduce hip strain during mounting, while the padded, contoured seats with breathable mesh fabric maintain proper spinal alignment. Independent testing shows our frame adjustments decrease pressure points by 42% compared to standard adult tricycles.
2. Dual Suspension with Variable Damping
To address uneven pavement and curb challenges in senior communities, we incorporate front fork suspension (50mm travel) combined with rear coil-over shock absorbers. The damping system features three resistance levels (low/medium/high) adjustable via a handlebar-mounted dial, allowing users to optimize ride quality based on terrain conditions. This dual suspension reduces vibration transmission to 3.2m/s² RMS, meeting ISO 2631-1 comfort standards for elderly transportation. The suspension components undergo 100,000-cycle durability testing to ensure long-term reliability.
3. Power-Assisted Pedal System with Smart Controls
Our proprietary 250W hub motor system provides pedal assistance up to 20km/h, with five adjustable power modes (eco/normal/high/turbo/thumb throttle). The LCD display shows speed, battery level, and assistance mode, while the regenerative braking feature extends battery life by 18%. The 36V lithium-ion battery (removable design) offers 40-50km range per charge and fully recharges in 4.5 hours. Safety certifications include UL 2849 and EN 15194 compliance, with thermal protection preventing overheating during prolonged use.
Manufacturing Process & Quality Assurance
Our production facility operates under ISO 9001 standards, implementing six-stage quality checks including:
-
CNC-machined frame weld inspections (tolerance ±0.5mm) -
Salt spray testing for corrosion resistance (1,000 hours @ 5% NaCl) -
Load capacity validation (static test: 150kg, dynamic test: 10,000km endurance) -
Electrical system waterproofing (IPX5 rating) -
Final assembly torque verification (DIN EN ISO 6742-2 compliance)
Customization Capabilities
We offer B2B clients:
-
12 color options with powder-coated finishes -
Seat upgrades (gel padding, orthopedic support) -
Accessory integration (basket mounts, LED lighting, GPS trackers) -
Fleet management solutions (IoT-enabled usage analytics)
Our products currently serve 320+ senior centers across North America and Europe, with a 97% customer retention rate. All designs undergo validation through geriatric physiotherapists and occupational safety experts to ensure optimal user experience.
