Bergamont E-Horizon Expert 600 Gent, e-bike road bike for commuting

Our review

This is an initial score and could change as I spend more time on the bike over its 12 months of testing. The bike is being used daily as I cycle around Bristol, my most common mode of transport at home
Pros: Responsive and amply powerful motor, sit-up position gives good visibility
Cons: The saddle isn’t to my taste, and I don’t rate the front light

The E-Horizon sits in Bergamont’s trekking family, and with full, latest-generation Bosch integration is built to make short work of cruising around town and venturing further afield.


It has a classic sit-up-and-beg shape, giving all-day comfort and great heads-up visibility, rather than a more racy position, which completely suits my plans for this bike.

The ‘600’ is the most up to date version, with a 625Wh PowerTube battery supplying the juice to the fourth generation Performance CX motor. On the bars by the grips are the mode toggle switches and the main Intuvia display, with all the data I’ll ever need.

The bike comes with a rack and integrated mudguards, as well as front and rear lights that plug straight into the main battery – there’s no chance of forgetting my lights now!

Should one wish, the bike is compatible with a piggy-back Bosch battery, for massive trekking ranges, though I doubt I’ll be using one.

While I can guarantee there will be comments telling me I’m lazy, and that I’m cheating, I don’t really care. This bike isn’t about getting fitter or faster, it’s about painless transport around Bristol, dodging the cars that clog the city’s arteries and avoiding getting sweaty in the process.

I do plenty of ‘real’ exercise in my day-to-day activities, this is merely a form of urban transport.

Bergamont E-Horizon Expert 600 Gent specification and details

Bergamont’s aluminium frame houses the PowerTube 625Wh battery in the down tube, and there’s potential to add a range-extending battery along the top of the down tube, plugging straight into the charge port that’s sat above the motor and protected by a rubber flap.

The motor itself has an extra plastic shroud that’s built as part of the Bergamont frame. The down tube and motor mount are common across Bergamont’s e-bike ranges, so it makes sense for the motor to have a touch extra protection, given that it also appears on its mountain bikes.

Cables and hoses run within the frame and there are two sets of bottle cage bosses – handy for hydration and, potentially, lock brackets.

The front of the bike has an SR Suntour NCX-E suspension fork with 63mm of travel to take a bit of the buzz from your hands. It also has a lockout to boost pedal efficiency, should you wish.

The bike’s motor helps drive the Shimano SLX 1×11-speed drivetrain, which is also protected from the elements, this time by a drivetrain cover – handily this means no trouser clips are required either.

Shimano also provides basic MT200 hydraulic disc brakes, along with the hubs for the wheels. These are built into 20mm rims and shrouded in e-bike-ready Energizer Active Plus tyres from Schwalbe, with a reflective strip around the sidewall.

The bike is completed with a number of handy accessories: there are sturdy-feeling front and rear mudguards, which integrate structurally with the rear rack, a set of B&M lights that plug straight into the bike’s battery and are controlled by the Bosch display and buttons, and there’s also a kickstand.

Finishing kit is all basic alloy equipment, with a very adjustable stem, and there are spacers with the bike that will make fitting a normal stem easy.

Without pedals, it weighs 24.5kg.

Why did I choose this bike?

I’m a long-time convert to the urban e-bike, especially ones that can haul a bit of luggage. However, cargo bikes are just a bit too bulky for everyday use and can be difficult to lock up at bike racks or in crowded bike lockups, and to fit into my occasionally crowded garage.

I could have chosen a regular ‘analogue’ commuter bike for 2020, however, in all honesty, getting to and from work is a chore, rather than a way of fitting in some exercise, so an e-hybrid makes sense for me.

It should offer sweat-free transport around town, and with a pair of pannier bags, enough load-carrying capability to do my weekly shopping.

The Bergamont itself has a nice upright position, which is fairly comfortable, and Bosch’s motor is a proven piece of equipment.

It was important for me that the bike came with mudguards, racks and integrated lighting too. I also wanted a bike that hovered below the radar because this bike will be locked up all over town, so I don’t want one that attracts too much attention.

Bergamont E-Horizon Expert 600 Gent initial setup

The E-Horizon was very easy to set up out of the box. The suspension fork needed minimal tweaking (and, if I’m honest, the biggest thing I’ll be sending it off is a curb) and the tyres have been inflated to around 40psi – enough to give a bit of comfort, without being too sluggish.

The stem’s adjustability meant I could drop it a little to lower the bars a touch, and I’ve angled the ‘paddles’ of the Ergon grips down too for cruisy-comfort.

The saddle is half an inch lower than it might have been, to make waiting at traffic lights a little less wobbly with a loaded pannier, and with the motor assisting, I don’t need my legs to be at their absolute optimum pedalling performance anyway.

Bergamont E-Horizon Expert 600 Gent ride impressions

As this is a bike for getting to and from work it’s not going to be pushed anywhere near its theoretical limits, and it’s not a bike that’s going to hold me back in any way either. As such, it’s been a very painless and relatively enjoyable introduction.

The Bosch motor is good, and having used it plenty of times before was a known quantity. I like the neat integration of battery, lights and Intuvia controllers into the bike, which make it feel like a very finished system. 

So far I’ve left it in Turbo – might as well make the most of the motor, right?! – and I’ve had just over 60km range from each charge, which is perfectly acceptable in my eyes.

I do need to remember though, that when the battery indicator gets towards the bottom there’s little notice of the battery actually cutting out, and it’s like riding through treacle when it does!

Riding the bike is comfortable, for the most part. The tyres are wide enough to give just enough compliance while maintaining decent rolling resistance, and I’ve had no grip issues either.

The brakes and drivetrain also perform as expected. One niggle is the saddle, though, which I haven’t got on with at all, it’s just the wrong shape for my bum.

The accessories are all acceptable too; the mudguards have kept me fairly dry and my Ortlieb panniers clip on with little issue (though I’d like the overall length of the rack to be a touch longer for future, bigger-load carrying options).

I have had an issue with getting the position of the front light correct. The beam has a very defined cut-off and only really has a strong pool of light in a limited area. This means it’s difficult to get it to throw enough light forward to spot pedestrians in dark clothing in un-lit areas and have a strong enough pool of light closer to me so I can dodge puddles/mud/dog eggs.

It’s frustrating to say the least because on my commute I cover a range of different paths and roads where I need a bit of everything.

Bergamont E-Horizon Expert 600 Gent upgrades

Going forward I’d like to keep it as stock as possible because this is a bike that should be spot on from the get-go, and one I don’t feel many other owners will be chopping and changing components on. The E-Horizon is more of a tool than a ‘hobby’ bike.

That said, the saddle has to go, and I’d like to explore lighting options too because I don’t feel the front light suits my needs.


The other project on the boil is security. Having had bikes stolen in the past, it’s something I’m keen to avoid. I’m working on a plan for a set of nicely integrable locks, but more on that next time.

BikeRadar‘s 2020 long-term test bikes

At the start of the year, every member of the BikeRadar team selects a long-term test bike to ride over the course of the following 12 months. Some choose a bike from their favoured discipline and ride it hard for a year, others opt for a bike that takes them outside of their comfort zone.

Our long-term test gives us the opportunity to truly get to grips with these machines, so we can tell you how they perform through different seasons and on ever-changing terrain.

We also use them as test beds for the latest kit, chopping and changing parts to see what really makes the difference – and help you decide which upgrades are worth spending your money on.
