Biomechanics & Comfort
Engineered for People, Not Just Performance.
Two decades of adult tricycle expertise, distilled into one thoughtfully engineered machine that keeps riders independent, active, and comfortable — for years to come.
From the universal joint in the steering column to the passivated disc rotors that resist corrosion in all weathers, every component reflects a deliberate engineering decision.
Zero Compromise Safety
Every Detail Has a Reason.
Low Centre of Gravity
The semi-reclined seating position places the rider's mass low and central. Combined with the stable three-wheel delta configuration, this geometry produces exceptional lateral stability — virtually eliminating tip-over risk at all speeds. Riders who have experienced balance issues on two-wheel bikes report immediate confidence on CHILL.
Ultra-Low Step-Through Frame
The low-slung alloy frame provides a minimal mount height, allowing riders to step on and off without swinging a leg high over the saddle. This is especially meaningful for those with hip or knee restrictions. Mounting and dismounting becomes a dignified, comfortable part of the ride — not an obstacle to it.
Wider Seat & Supportive Backrest
The wide, 42 cm mesh seat with integrated breathable backrest redistributes rider weight across a larger surface area. This dramatically reduces pressure on the lower spine, hip joints, and wrists — making CHILL a genuine therapeutic option for riders with back pain, reduced mobility, or post-operative restrictions.
Height Adjustable
The stem angle is adjustable to accommodate riders from 1.50 m to 1.95 m in height. In the meanwhile, both the seat base and backrest adjust independently, allowing the rider to fine-tune height, reach, and recline angle. Whether short or tall, upright or reclined — CHILL fits you, not the other way around.
Hands-on-Bar at All Times
Thanks to the intuitive universal joint steering geometry, riders never need to release the handlebars to manoeuvre through tight corners or slow-speed environments. Both hands remain on the bar at all times — elevating safety, control confidence, and rider stability, particularly during low-speed urban navigation.
Electric Assistance That Feels Natural
Power comes from a Ananda M100 mid-drive motor, delivering up to 120 Nm of torque(Rear Hub Motor also can be customized). Assistance can be pedal-activated or throttle-controlled, giving riders flexibility depending on energy levels, terrain, or personal preference.This setup provides strong hill-climbing ability without sudden surges.
Passivated Anti-Rust Hydraulic Disc Brakes
CHILL's Hydraulic disc brakes with 3 mm rotors—thicker than most cargo tricycles—deliver strong, controlled stopping power with minimal hand force. It undergos a professional passivation treatment — an electrochemical process that forms a protective oxide layer on the steel surface. The result: rotors that resist corrosion in wet, salted, or coastal environments.
Practical Detachable Rear Basket
A removable rear basket adds everyday practicality. It detaches in seconds and doubles as a shopping basket, then clips back on just as easily. When removed, the rear rack remains available for other cargo needs.
All-Round Safety Lighting System
CHILL is equipped with integrated LED lighting and indicators designed for real-world visibility. The front headlight outputs 40 lumens and is controlled directly from the handlebar. At the rear, a combined LED taillight and brake light ensures visibility when slowing down, while indicators remain visible from both rear and side angles—crucial at intersections and shared paths.

Your Body Will Thank You.
What truly sets trike bike CHILL apart is its riding posture. Instead of a forward-leaning or upright stance, riders sit lower with proper back support and an evenly distributed weight profile. This semi-recumbent position significantly reduces strain on the knees, hips, lower back, shoulders, and wrists.
For many riders, the difference is immediate. The bike feels planted and predictable from the first pedal stroke, especially at low speeds or when stopping and starting. This design philosophy aligns with a broader European shift toward inclusive cycling, explored further in deep analysis:

Easy Access, Intuitive Control
CHILL is designed so riders do not need advanced cycling skills. The low step-through frame makes getting on and off straightforward, even for riders with limited flexibility. Controls are simple and clearly laid out, allowing users to focus on the ride rather than the mechanics.
A common piece of user feedback in adult mobility cycling is the fear of “not being skilled enough.” CHILL removes that barrier. If you can rotate the pedals, you can ride again—with electric support that feels smooth, predictable, and reassuring.
This stability is particularly valuable for those exploring an electric tricycle for seniors, where safety, predictability, and control matter more than speed. For a broader look at this category, see Electric Recumbent Tricycles Built for Comfort, Stability, and Long-Term Riding.
Comfort You Can Adjust—Precisely
Comfort on CHILL is not a fixed setting. It is adjustable in detail.
The seat base measures 42 cm wide, offering generous support without pressure points. A breathable mesh backrest provides comfort in all weather conditions without trapping heat. Both the seat base and backrest adjust independently, allowing the rider to fine-tune height, reach, and recline angle.
Suspension further enhances ride quality. Fully adjustable and working in harmony with the seating system, it smooths out uneven paths, curbs, and everyday road imperfections. The result is a ride often described as “effortless” and “surprisingly smooth.”
Thoughtful Safety and Practical Features
CHILL is equipped with integrated LED lighting and indicators designed for real-world visibility. The front headlight outputs 40 lumens and is controlled directly from the handlebar. At the rear, a combined LED taillight and brake light ensures visibility when slowing down, while indicators remain visible from both rear and side angles—crucial at intersections and shared paths.
A removable rear basket adds everyday practicality. It detaches in seconds and doubles as a shopping basket, then clips back on just as easily. When removed, the rear rack remains available for other cargo needs.
Hydraulic disc brakes with 3 mm rotors—thicker than most cargo tricycles—deliver strong, controlled stopping power with minimal hand force. A built-in parking brake secures the trike on slopes or in public spaces.
Designed for Real Life, Not Just Specifications
CHILL uses an 8-speed shift system that allows gear changes even when not pedaling—an often-overlooked advantage for stop-start riding. The control display is clear, readable in daylight, and customizable, showing only the information the rider finds useful.
Everything is operated from the handlebars, keeping hands on the grips and attention on the path ahead.
CHILL is a recumbent electric tricycle for adults who value comfort, confidence, and independence. For some riders, it is the difference between staying home and getting back out into the world. For others, it is simply the most comfortable way they have ever moved through their city or neighborhood.
It represents nearly two decades of experience in adult tricycle design—distilled into one carefully engineered electric trike that prioritizes people over performance.
