The Complete DUOTTS 2026 Range Guide: Which Model Fits You?

Quick answer: which DUOTTS to pick

Before the detailed specs, here are the three main directions in the DUOTTS range at All4eBikes:

Hub motor vs Bafang mid-drive: which to choose

9 of the 11 DUOTTS models use a rear hub motor — simple, robust and minimal maintenance. Only two models, E26 and E29, use a centrally-mounted Bafang mid-drive motor with an integrated torque sensor.

The practical difference: a hub motor pushes the wheel regardless of exactly how hard you pedal (based on throttle or cadence sensor), while a Bafang mid-drive with a torque sensor measures your actual pedaling force and amplifies it proportionally — a more natural feel, but at a 30-50% higher price.

The C29 family: the most varied

The C29 family covers four variants — Lite (250W), Max (500W), L (750W) and K (750W with a huge 37.5Ah battery) — all on the same base geometry but with different power and range configurations. It's the ideal starting range if you're not sure how much power you need.

The F family: from commuting to serious off-road

F26 Lite (500W) leans towards commuting and paved roads, while F20 (750W, 52V 27Ah battery) and F26 (1500W) move towards mixed terrain and long distances thanks to their large battery capacity.

N26 and S26: the 1500W fat bikes

Nearly identical on paper (1500W, 48V 20Ah), N26 and S26 are the most powerful hub-motor models in the range, built for rough terrain and riders who want maximum power without stepping up to mid-drive. Read the full hub vs mid-drive comparison to understand the technical difference better.

Estimated range by battery family

Real-world range depends on load, terrain and assist level used — see our complete guide to calculating real e-bike range for the methodology. As a general reference, based on battery capacity (Wh):

• 468-648Wh (C29 Lite, E29): roughly 35-55 km at moderate assist
• 720-864Wh (C29-L, C29 Max, F26 Lite): roughly 45-65 km
• 960Wh (N26, S26, F26, E26): roughly 55-75 km
• 1,400-1,800Wh (F20, C29-K): roughly 70-100+ km, the largest in the range

DUOTTS vs building your own conversion kit setup

A fully-assembled DUOTTS and a standard bike fitted with a conversion kit solve the same problem from opposite directions. A DUOTTS arrives factory-matched: motor, battery, controller, frame and brakes are all specced to work together, tested as a unit, and ready to ride with no compatibility questions to figure out.

Building your own is the better route if you already have a bike you like and want to keep, or if your ideal spec (a specific frame geometry, a particular power level, or a battery capacity that doesn't match any stock DUOTTS configuration) doesn't exist as a factory option. It also tends to work out cheaper if you already own a suitable donor bike. Our step-by-step conversion kit installation guide and full cost breakdown for converting a bike cover what that route actually involves. For a broader look at how the Romanian conversion kit and e-bike market fits together, see our beginner's guide to the e-bike conversion kit market.

S26 vs N26 and other close comparisons

A few pairs in the range look nearly identical on paper, which makes them the models customers ask us about most. S26 and N26 share the same 1500W motor and 48V 20Ah battery, so the differences come down to frame details and finish rather than raw performance — see our dedicated DUOTTS S26 vs N26 comparison for the specifics if you're choosing between the two.

Within the C29 family, the decision usually comes down to how much battery you actually need: C29 Max (48V 18Ah) covers most mixed-terrain riding comfortably, while C29-K's much larger 37.5Ah battery only pays off if your typical ride is long enough to actually use that extra capacity — otherwise you're carrying extra battery weight for range you won't use. If you're unsure whether you need a hub motor or a mid-drive at all, our hub motor vs mid-drive comparison covers that decision independently of which specific model you're considering.

Who each model is really for: rider profiles

Specs matter, but matching a model to how you'll actually use it matters more. Here's how the range breaks down by rider intent:

• Daily city commuter: C29 Lite or F26 Lite. Light, efficient, and enough range for most urban round trips — see our guide to daily e-bike commuting for how the savings and time comparison against a car actually works out.
• Rider who occasionally carries cargo or a passenger: C29 Max or C29-K, both with enough motor headroom and battery capacity to handle extra weight without straining. Our guide to cargo weight limits explains how added weight affects motor and battery demands, and the same logic applies to a fully-assembled bike.
• Long-distance or hilly-commute rider: F20, with its large 52V 27Ah battery, is built specifically for distance without a mid-ride charge.
• Off-road or fat bike rider: S26 or N26, both 1500W with wide tires for sand, snow and rough trails.
• Rider who wants the most natural pedaling feel: E26 or E29, the two Bafang mid-drive models with a torque sensor, at a higher price than the hub-motor models.

Keeping your DUOTTS running long-term

A factory-assembled bike still needs the same basic upkeep as a converted one: brake pads, tires and drivetrain wear with distance, and the battery is the component most riders underestimate. Battery lifespan depends heavily on charging habits — avoiding full discharges, not leaving it at 100% for extended periods, and storing it correctly in cold weather all measurably extend how many charge cycles it delivers before capacity noticeably drops. Our battery lifespan and maintenance guide covers the specifics, and the same principles apply whether the battery came on a DUOTTS or as part of a conversion kit.

For general upkeep beyond the battery, our complete maintenance guide and common problems guide apply equally well to a factory-built e-bike, since the underlying motor, controller and battery technology is the same either way.

What to expect after ordering: delivery and first-ride checklist

DUOTTS bikes typically arrive partially assembled rather than fully built out of the box, which keeps shipping practical for a full-size electric bike. Expect to finish a short final assembly — usually fitting the front wheel, handlebar, pedals and seat post, and connecting the display and any remaining cabling — before your first ride, along with charging the battery to a full charge rather than riding straight off whatever charge it arrived with.

Before you head out for the first time, run through a quick check regardless of how confident you feel with bikes generally: pedals and handlebar torqued to spec and not loose, tire pressure at the recommended level, brakes engaging firmly with no excessive lever travel, and the battery firmly seated and locked rather than just resting in its mount. These are the same basic checks worth doing periodically afterward too — our maintenance guide covers a fuller ongoing checklist. If anything feels off on arrival or during assembly, contact All4eBikes support before riding rather than after.

Frequently asked questions about the DUOTTS range

Conclusion: how to choose from the DUOTTS range

Simple rule: start from your daily use case, not from the wattage number. For city commuting, a C29 Lite or F26 Lite is enough and more affordable. For mixed terrain and longer distances, step up to C29 Max or C29-K. If you want maximum power and fat tires for any terrain, S26 or N26 are the right pick, and if you want the feel of a premium mid-drive with a torque sensor, E26 is the only model in the range that offers it.
