Trek Allant+ 6

The Trek Allant+ 6 turns the jobs that usually involve a car, a sweaty climb or a careful weather calculation into straightforward bike journeys. It is a powerful electric hybrid for commuting, errands, touring, towpaths and smoother gravel, with flat-bar control, useful luggage equipment and strong Bosch assistance when the road tips up. The current UK model is offered with conventional, Lowstep or Midstep frame forms, and the battery fitted to an offer can be 400 Wh, 545 Wh or 800 Wh.

Trek Allant+ 6 prices and live UK offers

The name covers several genuinely different configurations, so battery capacity and frame shape matter more than a retailer-applied year label. A 400 Wh Lowstep keeps the choice focused on shorter routine rides and easier mounting. The 545 Wh conventional and Midstep options make a sensible middle ground for many commuters, while the 800 Wh conventional and Midstep versions suit longer, hillier routes or a life where charging is less frequent.

There is no dependable single range figure for an Allant+ 6. Hills, wind, temperature, assistance mode, tyre pressure, rider weight, luggage and battery capacity all alter how far it will go. Plan around the journey you repeat most often, plus the charging opportunities at each end, rather than buying maximum capacity by default.

What is the latest Trek Allant+ 6 generation?

The current UK model belongs to the Allant+ 5 and 6 Gen 2 family. Its Bosch Performance Line CX Smart System motor has 250 W rated continuous output, a factory-listed 85 Nm and assistance up to 25 km/h. That is useful power for pulling away with panniers, keeping momentum on a steep suburb-to-station climb, or taking the sting out of a loaded day ride. Kiox 300 and the LED Remote provide the system controls and connected functions through the eBike Flow app.

Assistance makes the Allant+ 6 feel lively within its supported speed range, but it remains a substantial, fully equipped e-bike once the motor cuts out. The 545 Wh conventional bike is published at 23.30 kg in size L, while a 545 Wh access-frame size M is published at 23.10 kg. Those figures do not apply to the 400 Wh or 800 Wh configurations.

Frame choices, sizing and how the Allant+ 6 should ride

Choose the conventional frame for the traditional high-step shape, available in M, L and XL. Lowstep and Midstep versions both make mounting easier, but they are not simply two names for the same frame. Lowstep has the lowest top tube, while Midstep has its own S, M and L geometry. Use the chart for the exact frame form, particularly if easy mounting is a key part of the purchase.

A 60 mm SR Suntour Mobie 34 air fork and 57-584 Schwalbe G-One tyres should smooth the sharp edges of potholes, broken cycle lanes and compacted gravel without the extra movement of rear suspension. The rigid rear, 27.5-inch wheels and broad tyres point towards a planted, predictable feel with luggage rather than a sporty, lightweight response. Four-piston hydraulic brakes with a 203 mm front rotor add welcome control for a heavy e-bike on road descents and smoother gravel.

The Allant+ 6 is well suited to maintained unsurfaced routes, towpaths and rougher everyday lanes. Its fork, tyres and rigid rear do not make it a technical mountain bike, so steep, rooty trails and bike-park riding are outside its brief.

Trek Allant+ 6 battery and frame options compared

• 545 Wh conventional: A balanced full-height option for regular commutes and leisure rides, with a published 23.30 kg weight in size L.
• 800 Wh conventional: The conventional-frame choice for riders prioritising battery capacity and longer gaps between charges. A complete-bike weight is not published.
• 400 Wh Lowstep: The easy-access option for shorter repeat journeys or buyers who want to keep initial battery capacity modest. No exact complete-bike weight is published for this configuration.
• 545 Wh Midstep: Combines the middle battery option with the Midstep frame, published at 23.10 kg in size M.
• 800 Wh Midstep: Pairs the Midstep layout with the largest listed battery capacity. A complete-bike weight is not published.

All current versions use Shimano CUES U6000 1 x 10 gearing with an 11-48 LINKGLIDE cassette. The broad low gear works alongside the Bosch motor on loaded climbs, while the derailleur drivetrain remains a conventional chain-based system rather than a low-maintenance belt drive.

UK maintenance, security and everyday ownership

Front and rear mudguards, wired lights, a kickstand and a MIK-compatible rear rack are fitted, so the Allant+ 6 can take on weekday work without an immediate shopping list of basics. The rack is rated for 25 kg, though rider, bike and cargo together must stay within the 136 kg system limit. That makes it a convincing choice for work kit, a pair of panniers or a practical food shop.

The externally mounted Bosch battery is removable, which is handy when the bike lives in a garage, communal store or shed while charging happens indoors. Secure ground-level storage is preferable to carrying this sort of e-bike upstairs every day. For wet-weather mileage, clean and lubricate the chain regularly, use compatible Shimano LINKGLIDE replacement parts, and ease off the pedals briefly when changing gear rather than shifting under full motor load.

The Bontrager Kovee rims are Tubeless Ready and there is clearance for tyres up to 27.5 x 2.4 inches. Suitable puncture-resistant tyres are a practical commuting upgrade, while a tubeless conversion needs compatible tyres, tape, valves and sealant. The rear wheel uses a 135 x 5 mm quick-release hub, so replacement wheels are available but premium off-the-shelf choice is narrower than for a modern rear thru-axle.

Current Shimano CUES build versus the previous Deore Stagger build

An older 2023 Allant+ 6 Stagger is a previous build, not the same specification as the current Gen 2 CUES version. It used Shimano Deore M5130 10-speed shifting with an 11-43 cassette. The current build moves to Shimano CUES U6000 and an 11-48 LINKGLIDE cassette, giving a lower climbing gear and a drivetrain designed for high-torque e-bike use. Midstep is the later public name for the access-frame option, so a Stagger-labelled offer deserves a close look at its displayed frame and drivetrain before treating it as equivalent to a current bike.
