Ecoco (37)

The current Kona Ecoco generation is a practical step-through e-urban platform built around a Shimano mid-drive system and a deliberately simple commuter chassis. Across the 2024 through 2026 model years, the published geometry remains unchanged, pointing to the same underlying frame: a low-slung aluminum frame with 650b wheels, a rigid aluminum fork, 450 mm chainstays, and integrated utility equipment. Kona’s choices here are straightforward rather than trend-driven. The semi-integrated battery layout, quick-release hub standards, and rigid fork all emphasize serviceability, durability, and predictable everyday use over novelty or performance signaling.

What distinguishes this Ecoco is how clearly it is aimed at paved urban riding and light mixed-surface use. The Shimano E6100 system used on the early version delivers moderate 60 Nm assistance rather than cargo-bike torque, while the 650b x 47c tire setup provides much of the comfort that other brands chase with cheap suspension forks. Compared with the earlier Ecoco, this generation sits a bit lower at the bottom bracket and presents a taller front end with shorter reach figures, reinforcing its more upright, accessible commuter intent. In the market, it sits in the mid-range utility e-bike category: more refined and mechanically sensible than many hub-motor budget commuters, but not positioned as a premium long-range or high-power urban machine.

Fit and geometry

The Ecoco’s geometry is firmly commuter-oriented, with a notably upright fit and stable wheelbase. In size M, the bike combines a 606 mm stack with a 422 mm reach; size L rises to 644 mm stack and 438 mm reach. Those are tall front-end numbers relative to the bike’s modest reach figures, and they point to a posture that keeps weight off the hands and improves visibility in traffic. The 70-degree head tube angle is relaxed for an urban bike, while the 450 mm chainstays are fairly long, both of which support calmer steering and better straight-line composure rather than quick, nervous responses.

The rest of the numbers reinforce that theme. Wheelbase grows from 1078 mm in S to 1144 mm in L, which helps the bike feel planted at city speeds, especially with the additional mass of the motor and battery. A 70 mm bottom bracket drop lowers the rider’s center of gravity for a more settled feel in corners and during stop-start riding. Seat tube angles steepen from 73 degrees in L to 75 degrees in S, a typical move to keep rider position consistent across sizes. Overall, the geometry favors easy mounting, a natural upright stance, and predictable handling over agility or sporty fit.

Builds

The available data points to at least two builds within this generation, identified as the 37 and 36SH, with later years representing spec revisions on the same frame rather than a redesign. The 2024 Ecoco is listed at $2,623 and uses a Shimano E6100 mid-drive motor with 60 Nm torque, a 504 Wh battery, a rigid fork, 650b aluminum wheels, Shimano hydraulic disc brakes, and a 9-speed Shimano Alivio/Acera drivetrain. That package makes the bike’s priorities clear: dependable assist, branded braking, and practical urban durability rather than premium drivetrain parts or suspension.

The broader generation story is that Kona updated equipment while keeping the frame constant. The 2025 version moved to Shimano CUES, and 2026 shifted to Shimano EP5/EN600 controls with a new cockpit, but the geometry stayed the same. That suggests buyers should think of these bikes as the same commuter platform with evolving parts packages. The value proposition is strongest for riders who care about the Shimano mid-drive system, hydraulic brakes, and commuter-ready wheel-and-tire setup more than they care about chasing the latest high-torque motor or luxury urban-bike finishing kit.

Reviews

Reviewers consistently describe the Ecoco as a balanced, easy-to-ride commuter rather than a high-performance e-bike. Opticycles highlights the Shimano E6100 mid-drive as a key strength, noting that its 60 Nm output feels smooth and predictable on mixed urban routes. That character comes through repeatedly in the reviews: the bike is praised for confident assistance on short to medium climbs, stable handling in traffic, and a generally low-fuss ride quality that suits daily transport. The rigid fork does not appear to be a major drawback in this context because the 650b wheels and 47 mm WTB Horizon tires are repeatedly credited with muting potholes and rough pavement while maintaining traction in wet city corners.

The weaknesses are mostly tied to the same design restraint that makes the bike approachable. Reviewers note that the motor is not especially punchy by current e-bike standards and lacks the explosive climbing power of higher-torque systems, particularly on very steep hills or when carrying heavier loads. The 504 Wh battery is seen as adequate for typical commuting, but less convincing for longer detours if the rider relies heavily on assist. Value assessments are similarly measured: the Ecoco is regarded as sensible rather than class-leading on price, with its case resting on the Shimano mid-drive, hydraulic brakes, and practical chassis rather than outright bargain pricing or standout performance.
