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.

The specification above is our standard EU configuration for the CHILL.
The CHILL is built on a configurable platform: motor, battery, controller,
gearing and tyres can be specified to suit your market. Units built for
other markets may differ from the figures shown here.
Designed Around the Rider It Is Meant For
The CHILL is semi-recumbent: the rider sits lower, with back support and weight carried through the seat rather than the hands and shoulders. Every dimension follows from that — the 380 mm step-through, the 580–707 mm seat height range, the 22° of backrest adjustment, the 1.6 m turning radius. Together they define a trike for people who want to keep cycling on their own terms, rather than one adapted from an upright bicycle.
Europe’s over-60 population is both growing and staying active longer, and what that group looks for has moved from mobility aids toward equipment that fits into an ordinary, independent life. The CHILL is built for that shift, and the seating geometry can be specified for markets whose riders sit outside the standard range.
How the CHILL Rides — and What Can Be Tuned for Your Market
Assistance that follows the rider
A torque sensor means the motor responds to how hard the rider is actually pedalling. We calibrate that response deliberately gently: the first few metres from a standstill are where a rider decides whether a trike feels safe, so assistance builds progressively rather than arriving at once. That is a calibration decision, not something that comes with the component.
Composure through a turn
The rear differential lets the two rear wheels turn at different speeds through a corner. Without one, the outer wheel has to cover more ground at the same rate as the inner, and the rider feels it as resistance at the handlebars. With one, low-speed manoeuvring stays predictable — car parks, narrow paths, turning in a driveway.
Configured to your market
Terrain, rider size and regulation differ market to market. Motor and battery can be specified to your terrain profile, a throttle fitted where regulation allows, gearing and tyres changed for rougher routes.CAN bus communication lets your service network read the system rather than guess at it. Because changing a motor changes what the battery and controller have to do, we match the control parameters to your specific combination and validate it as a set before sample approval — which is why we calculate gradeability for your build rather than publishing one figure.
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.
