Modular Cargo Bike for Commercial Applications
The UM FRONTIER is a commercial-grade long-john electric cargo bike built for operators focused on daily delivery runs. Its reinforced modular frame delivers a 300 kg GMV on every delivery route.
Features include a 340-litre lockable weatherproof cargo box, dual-battery long range, one-touch electronic reverse and rod steering — engineered for low-maintenance fleet deployment.
Consistent performance, shift after shift.
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.
Compact Long-John UM Frontier
OEM-Ready Cargo Bike Platform
Built to support customization at scale — from frame design to component integration.

Reinforced Modular Frame
The FRONTIER's head tube junction features a structural gusset plate — a load-bearing reinforcement engineered specifically for the sustained stress of 130 kg commercial payloads across daily multi-stop delivery routes. The same frame supports enclosed box, open deck, and dual-zone configurations without a chassis change — giving fleet operators a single platform that adapts to different commercial applications without secondary inventory investment.
340L Lockable Cargo Box with Half-Open Lid
A 340-litre enclosed cargo box delivers industry-leading volume for a long-john platform in this class. The lockable half-open lid allows operators to access the top of the load without fully opening the box — faster stops, more secure contents at the kerb, and less weather exposure during high-frequency urban delivery. The full locking system protects payload between stops across high-traffic environments where unattended cargo is a real operational risk.
Tough, Weatherproof Cargo Box
A hardwood panel construction with a welded aluminium alloy frame delivers structural rigidity that outlasts plastic alternatives under daily commercial loading. The foam-lined interior cushions payload against road vibration and impact across multi-stop delivery routes — protecting contents without secondary packaging. Fully sealed against rain and road spray, the box is built for year-round urban operation, not just dry-weather use.
Dual-Battery System for Longer Range
A 48V/15Ah integrated battery handles standard daily routes. The optional 48V/14Ah external battery extends operational range without returning to depot — critical for fleet operators running multi-zone delivery circuits, back-to-back shifts, or routes in hillier urban terrain where motor demand is higher. More range per bike means more billable runs per shift — the metric that drives cargo e-bike fleet ROI.
Front + Rear Dual Load Zones
The FRONTIER runs a front cargo box and rear platform simultaneously — two independent load zones operating at the same time, not as alternatives. For food delivery, express courier, and retail restocking, the ability to separate cargo types, maximise volume per trip, and reduce the number of runs per route is a direct operational cost reduction. More payload per trip. Fewer trips per route. The maths is straightforward.
One-Touch Electronic Reverse
Electronic reverse eliminates the need to dismount and manually manoeuvre a fully loaded bike out of loading bays, narrow delivery alleys, or congested urban staging areas. At 300 kg gross vehicle weight with a fully loaded 340L box, this is not a convenience feature — it is a daily operational necessity that experienced delivery riders consider non-negotiable.
Height Adjustable Stem & Seatpost
Different riders, different shifts, same bike. The FRONTIER's stem adjusts independently in both height and angle, while the adjustable seatpost accommodates a full range of rider builds — no tools, no downtime between handoffs. For fleet operators running shared vehicles across multiple drivers, a bike that fits every rider out of the box is not a comfort upgrade; it is an operational efficiency.
Boost Start Mode
A fully loaded FRONTIER at 300 kg gross weight demands consistent, controlled power at the moment of re-acceleration. Boost Start Mode provides immediate torque from a standing stop — keeping the bike moving predictably through stop-start urban delivery circuits without the lag that fatigues riders and slows route times. Available on both mid-drive and hub motor configurations.
AirTag FindMy + Anti-Theft Lock
AirTag-compatible GPS tracking and a factory-integrated anti-theft lock protect fleet assets across high-traffic environments where cargo bike theft is an established operational risk. Locatable and lockable from the factory — not retrofitted after an incident.
USE CASES
Designed for versatility, enabling seamless adaptation across multiple use cases and custom builds.
The UM FRONTIER is purpose-built for: last-mile and express delivery fleets replacing cargo vans on urban routes; food delivery operators requiring secure, high-volume payload capacity; retail and logistics businesses restocking urban locations; and municipal operators running maintenance or collection circuits in bike-lane-accessible zones.
