Reviews Trek Allant+ 8 – Electric bikes – Bikes

Trek is targeting its Allant+ line of e-bikes at “committed” commuters. The design and specification of its Allant+ 8, which sits a rung below the top-end £5,000 Allant+ 9, ticks all the right boxes for commuters of any distance.

Most notably, the Allant+ 8 has a high-powered motor and an equally high-capacity 625Wh battery, which promises to deliver very good range.

Trek Allant+ 8 Details and Specs

Trek’s Allant+ 8 features a hydroformed aluminum frame with all the accessories you’re likely to need, including fender mounts, rack bosses, dual water bottle cages and even undermount mounts. the top tube for a bag that fits the frame.

The accessory pack is just as comprehensive. It comes with sturdy aluminum mudguards, a minimal rear rack, battery-powered front and rear LED lights, a kickstand and quality pedals designed to grip your cycling shoes without damaging their soles.

The slim rack is rated at 14 kg / 30 lbs. That should be enough for a trip to the shops, where you’ll appreciate the inclusion of a kickstand. A stand really comes into play when the total weight approaches 40 kg.

The front light is rated at 180 lumens/60 lux, which I found to be more than enough to light the way on unlit suburban roads and rural lanes.

The range starts at £3,100 for the Allant+5 and goes up to £5,000 for the Allant+9, which comes with a Gates belt drive and high-tech hub CVT – continuously variable transmission – from Enviolo (formerly NuVinci), rather than a traditional derailleur or hub gears.

The heart of the bike is Bosch’s powerful CX Performance mid-motor. The CX is typically found on high-performance e-MTBs and the 85Nm of torque it provides is enough to get you and a fully loaded bike up steep climbs without breaking a sweat.

The Bosch system offers four assist modes: Eco, Tour, Sport and Turbo. The Eco setting offers the lowest level of assist but the highest potential range, around 90 miles, and at the other end of the scale the Turbo setting gives you the maximum power available but reduces the range to around 50 miles.

The large potential range is due to Trek specifying Bosch’s highest capacity battery, at 625Wh. It’s neatly housed in the downtube, using Trek’s RIB (Removable Internal Battery) system. Turn the key and the battery pops out from the top. It is easy to remove and it comes with a handle, which makes it easy to load from a distance.

Charging takes just under five hours, which is forgivable considering the extended range offered by the high-capacity battery.

The CX engine is controlled by Bosch’s Kiox color display and bar-mounted remote control. This means that you have plenty of information and you can also download routes from cycling apps such as Komoot.

The display is fully customizable via the Bosch app, and everything is done quickly and smoothly via Bluetooth.

As with all road e-bikes in the UK, the Allant’s electric motor only engages when you pedal and more importantly it will stop providing assistance at 15.5mph as required by law in vigor.

However, the regulations allow a 10% margin, which could put you over 17 mph. The Trek uses that headroom, with the Allant + 8 rolling fast on its bulky 2.4-inch 650b tires.

When testing in hilly terrain, and using each mode sparingly, I was able to achieve a maximum range of 93.8 miles/150.9 km, with a considerable ascent of 3,720ft/1,134m – which is really very impressive.

If you don’t need such an extended range, the Allant+ 7 is £600 cheaper, and its 500Wh battery should still be good for over 60 miles. If you want to increase the range even further, you can add Bosch’s 500Wh RangeBoost battery, offering around 60 extra miles, but it’ll cost you an extra £950.

The Allant’s downtube is offset, ensuring a perfectly aligned drivetrain. The result is smooth, reliable and quick shifting without chatter at either end of the cassette.

The gearing pairs a single 42-tooth chainring with a wide-range 11-42 cassette, and the 1:1 bottom ratio is low enough to pedal most hills, even without motor assist.

Slowing and stopping a 25kg bike requires powerful brakes, and the Allant doesn’t disappoint here, with Trek pairing Shimano’s MT200 twin-piston hydraulic brakes with large-diameter 180mm rotors more commonly found on mountain bikes.

The lever shape suits all hand sizes, and although the levers are initially soft, they offer plenty of bite throughout their stroke.

On e-bikes and hybrids, many brands tend to opt for a suspension fork for comfort, which adds both complexity and weight. I much prefer Trek’s approach, which instead relies on a stiff fork in combination with high volume tires and excellent contact points for ride comfort on the bike.

The 180-lumen front light should suffice for suburban adventures.

The Bontrager Commuter Comp saddle is well shaped and the padding isn’t too soft or firm, making it a great balance point. The ergonomically shaped grips eliminate frontal vibrations well and the huge tires easily adapt to excursions on gravel tracks, bridle paths, towpaths and side roads.

The Allant blows away, carrying everything in its stride. Its position is upright, comfortable and very well suited to driving in traffic, as you have a great view from the dominant seating position.

The steering is light and the bike is more nimble than any bike of this weight has the right. I found it easy to navigate through cycle path gates and around obstacles on narrow towpaths.

Although the price tag can be daunting, the Trek Allant+ 8 is a serious e-bike for commuters looking to expand their horizons.

The ride is infinitely comfortable, the large capacity battery provides ample range, and the bike comes with a full set of parts. There’s a lot to love here.
