FLYER Gotour 7.23: Review of a Comfortable, Powerful, and Heavy Bike

FLYER has been building electric bikes for decades, and the Gotour series is the comfortable touring line in the Swiss catalog.

The Gotour 7.23 was clearly a high-end model right from its launch: a Bosch Performance Line CX mid-drive motor, a built-in 750 Wh battery, an Enviolo continuously variable hub, and a Gates belt.

FLYER Gotour 7.23 Specifications (2023/2024)

This review covers the 2023 and 2024 models. This distinction is no mere detail. FLYER later reused the name for a bike equipped with an 800 Wh battery and an automatic transmission. If you’re looking for a used model, you’ll mostly come across the older version, both at retailers and in our selection of refurbished FLYER e-bikes.

Motor, battery, and range

The Gotour 7.23 is powered by the Bosch Performance Line CX from the Smart System, which delivers 85 Nm of torque. This is Bosch’s most powerful motor line, designed for challenging terrain and also used on trekking bikes. On a touring bike built for Belgian roads, this is plenty of power: a bridge, a dike, or a long climb won’t throw this motor off its stride. The assist responds immediately to pedal pressure and is clearly noticeable when starting off in the highest mode. Since the motor is centrally mounted, weight distribution is better than with a motor in the front or rear wheel. You’ll find more technical details in our article on the lifespan of the Bosch Performance Line CX motor. Torque indicates pulling power, not speed: this motor also stops providing assistance at around 25 km/h.

The battery is a built-in Bosch PowerTube 750. I’m deliberately not giving a fixed range. With a power consumption of 6 to 12 watt-hours per kilometer, you’ll theoretically get between 60 and 125 kilometers of assistance. Wind, temperature, tire pressure tires, cargo, and the selected mode all determine where you’ll fall within that range. In winter, the range decreases noticeably, as we explain in our article on the real-world range of an e-bike.

For most cyclists, I find these 750 watt-hours to be more than sufficient. If you ride 12 kilometers a day to work, you’re carrying capacity and weight that you rarely use. If you go on back-to-back 70-kilometer weekend rides or go on vacation with panniers, you’ll get the most out of it. The same reasoning applies to most electric hybrid bikes in this category.

Enviolo hub and Gates belt

This generation of the Gotour 7.23 uses an Enviolo TR hub. It does not have fixed gears: when you turn the lever, the pedaling resistance changes gradually. This is nice when starting off, since you can also make the gear ratio lighter while stationary. However, continuous variation does not mean it’s automatic. On this mechanical version, you operate the lever yourself; only the next generation features the Enviolo Automatiq. Under heavy motor load, the lever becomes harder to turn, so it’s best to shift gears by easing up slightly on the pedals. If you’re coming from a bike with derailleurs, the lack of distinct shift points takes some getting used to.

The drive system uses a Gates Carbon Drive CDX belt. It’s quiet, doesn’t leave grease stains on your pants, and doesn’t need to be lubricated. While it’s maintenance-free, that doesn’t mean it’s maintenance-free. The tension and alignment must be correct, and both the belt and the sprockets wear out. Chain lube should never be used on it. Whenservicing your e-bike, have the belt tension measured: relying on feel alone lacks precision. A squeaking belt most often indicates incorrect tension or misalignment, not a lack of lubrication. A complete comparison of the two systems can be found in our article on choosing between a chain and a belt.

"For me, this combination is the main reason to consider a Gotour over a comparable derailleur bike: you can ride for months without having to think about the drivetrain."

There is, however, a trade-off. A hub gear system is less efficient than a well-maintained derailleur and offers less gear range for steep, sporty climbs. If that’s what you’re looking for, a chain-driven trekking bike like the Cube Kathmandu Hybrid will suit you better; we go into detail about it in our comparison of Cube e-bikes. Even without assistance, you’ll feel the weight: thirty kilos, wide “ tires ,” and a hub make pedaling with the motor off a real chore.

Handling, Comfort, and Weight

Comfort comes from three sources: 60-millimeter-wide Schwalbe Al Grounder tires , a Suntour Mobie25 fork with about 75 millimeters of travel, and a suspension seatpost. On cobblestones and poorly maintained bike paths, each component absorbs some of the vibrations. On smooth asphalt, the bike feels stable and composed, even if the steering isn’t the most responsive. The Gotour encourages a steady ride, not a sudden acceleration at every red light. In turns, the bike’s weight and wide tires inspire confidence, but it requires more pressure on the handlebars than a lightweight city bike. Pack your panniers so that the weight is roughly balanced between the left and right sides. It handles gravel roads and forest trails very well, but it’s not a MTB.

The weight is the real weak point. Depending on the frame and size, the bike weighs between 30 and 32 kilograms. While riding, the motor largely masks this weight. But when it’s time to park it, turn around in a narrow hallway, carry it down a basement staircase, or hoist it onto a bike rack, you feel every kilogram. In my view, this isn’t a flaw that can be easily overlooked given the bike’s other qualities, but a question you need to answer honestly before buying: Can you get this bike out of your storage room on your own? On the other hand, the maximum load capacity of about 150 kilograms makes it well-suited for heavier riders and bulky luggage.

FLYER offers bikes with a low-step frame, a trapeze frame, and a diamond frame. The low-step frame is ideal for riders who want an easy step-through, while the diamond frame feels more stable when the panniers are full. For long-distance commuters and weekend touring cyclists, it’s one of the most well-designed bikes in its class. If you can store it on the ground floor and regularly ride thirty kilometers or more, you’ll get the most out of its strengths. For short urban trips and train commutes, it’s too big a bike.

Buy a used Gotour 7.23

The name “Gotour 7.23” has been used across several generations, and designations like “Gotour7,” “G1,” and “G2” are often used interchangeably. So look at the components installed, not the model year listed in a classified ad. A 750 Wh battery with a twist grip that isn’t automatic indicates the generation featured in this review. An 800 Wh battery with Enviolo Automatiq is a different bike.

The battery deserves the most attention. Low mileage doesn’t mean much if the bike has been sitting idle for a long time while fully charged—or, conversely, completely drained. Ask for a measured residual capacity, test the bike at a lower charge level, and perform a few short bursts of acceleration in the highest mode. If the battery cuts out under load, that’s a bad sign.

The Enviolo hub must shift smoothly from low to high gear, without any play or leakage. The belt must not have any damaged teeth or frayed edges. Also check the seatpost, fork, and FLYER-specific parts: the rack, battery cover, and frame mounts are less universal than Bosch components. Finally, consider the practical aspects: does the bike fit on your bike rack without exceeding the rail limit, is there a spare key for the battery lock, and do your own panniers fit the luggage rack system?

I find the Gotour 7.23 more appealing as a refurbished model than as a “ new.” The price drop is significant, whereas a 750 Wh battery in good condition and a CX motor don’t become outdated just because a newer display has come out in the meantime.

"A low price never makes up for a poor battery."

If a more extensive dealer network in Belgium is important to you, you can compare it to the Gazelle Ultimate C380, which features a similar combination of Enviolo and a belt drive. We mention it in our selection of the best belt-drive e-bikes.
