Folding the Gocycle G4 e-bike in the test: a relentless high-tech projectile

Josel G4

This e-bike is quickly gaining attention. In testing, the Gocycle G4 presents itself as a mature folding e-bike suitable even for touring. We make a flutter with a moth.

Sit and forget it’s a folding bike

With the Gocycle G4, you can sweep at breakneck speed, ride on long rides, get a jealous look, and let cyclists hang out on the mountain—then you fold the thing up in 10 seconds and it disappears on the subway home. There is no other folding e-bike that we know of that offers such a wide range of uses at such a high level. However, fourth gear fits the e-bike well.

We loved it

  • thoughtful concept
  • Very good folding mechanism
  • Quiet and powerful engine
  • traction control
  • cleanly wrapped
  • replaceable battery

We didn’t like it

  • Fourth gear missing
  • Many functions only via the app
  • The light cannot be turned off manually

In 2019, we tested the Gocycle GX for you. With the Gocycle G4, the successor is now on the farm. He should do much better. The basic principle remains the same: the e-bike fits in the luggage compartment or in the luggage compartment of the train and can be folded or opened again in ten (!) seconds. And there’s a boost button that pulls the corners of your mouth up.

This is new for the fourth generation

The main point we criticized at the time was the engine in the front wheel and the engine control. In our opinion, the drive developed by the manufacturer was quite high in work. It also pushed for a while, even though we had long since stopped pedaling. The manufacturer now wants to improve this.

Also new is carbon fiber (G4i), which helps in weight loss. The folding e-bike weighs 17.6 kilograms without the standard main rack, which is reminiscent of a motorcycle. MotoGP’s high performance tires are engineered to increase riding comfort.

The USB port on the handlebar, which now charges the smartphone while riding, is very welcome. Since our Gocycle still only has a rudimentary LED strip to show battery level and no screen to show speed, this is a reasonable update.

Upgrade equipment and standard prices

Standard equipment is also more extensive. Mudguards and bright LED lighting, previously subject to an additional fee, are now available in earlier works. Customers are happy to take that with them, because an elaborately designed Gocycle isn’t cheap.

The manufacturer estimates the Gocycle G4 that we tested here at a price of 4,299 euros. The better-equipped G4i (including digital cockpit, stunning LED daytime running lights, longer range and electronic gearshift) costs €5,499. The GoCycle G4i+ Special Edition, which is lighter thanks to the carbon wheels, is the spearhead of the group. The price here is 6,499 euros.

First impression and folding mechanism

Up to 6,500 euros for a folding bike! This is an advertisement. But as soon as the Gocycle appears in front of you, it becomes clear where the high price comes from. Especially when compared to much cheaper folding bikes like the Fiido D11.

Wherever we look, we discover well-thought-out details that we don’t know from any other e-bike. This also applies to the basic G4 variant available to us. The innovative folding mechanism with sturdy safety hinges instantly instills confidence in the technology.

The use of a single titanium pin is said to make the joint more robust and durable compared to the previous generation. The principle remains unchanged compared to the GX. Good thing – the folding process works within 10 seconds, as you can see in the following video of the previous model.

In the video you can see the previous model Gocycle GX. It shares many similarities with the G4 reviewed here. However, there are some important differences, which we will discuss in the text.

Driving test: 60 kilometers across Sauerland

Folding bikes are usually reserved for the city. The beauty of the Gocycle is that it is not limited to the city. Mature ergonomics, high-quality components and fine workmanship allow for longer trips without any problems.

As part of this test, we repeatedly rode through town with a G4, as with other e-city bikes we’ve been testing for you. We took it on a long ride in Sauerland to test the range. Starting at Kahler Asten, the second highest mountain in North Rhine-Westphalia, the approximately 60-kilometer route drove mainly over forest trails.

The rear spring element contributed to the “ride” just as comfortable as the new tire compound from Vredestein. Originally designed for asphalt, it also provides adequate grip on dry soils.

Scale and boost button

Gocycle limits the G4’s battery range to up to 60 kilometers. We can confirm that. Mostly in power-saving mode, we still had plenty of capacity left at the end of the run. This is despite the fact that the boost button has been used quite diligently in the meantime.

Like the VanMoof S5, the Gocycle folding e-bike also offers this button on the handlebars. Turn it on and the front wheel drive will instantly provide full torque, no matter what support position you just selected. The traction control effectively prevents the wheel from spinning.

Circuit lacks extra speed – not only in fast “USA Mode”

There are hardly any changes to the app. As a small special feature, the manufacturer offers you the opportunity to create and save performance profiles yourself. The first time the smartphone was paired with the bike, there was a firmware update that we installed. Subsequent pairings worked without any problems.

You have the option to trick the app into believing that the location is wrong. If you choose North America, it will unlock at a higher speed than allowed as normal. The Gocycle motor then supports your pedaling movements after 25 km/h allowed up to 32 km/h.

This is really illogical. Because the translation of the three-speed gearbox does not match this speed. Anyone who treads in third gear at a speed of more than 30 km/h quickly encounters him as a clown. In general, we often wanted a fourth gear such as a comfortable “overdrive” on flat surfaces or slopes.

The engine is now noticeably quieter and can be dosed more precisely

The biggest change is in the front wheel. The current Gocycle G4’s engine operates more consistently than it does on the GX. It provides significantly more torque on the mountain and no longer drives when we stop pedaling.

To our delight, it has also become noticeably quieter. The disc brakes we complained about in the first test also hold up hard, and are now larger and lighter. You see – the manufacturer improves its model from year to year and listens to customer feedback.

There was no reason to change the encapsulated chain, which will never come in contact with it and thus not get your fingers or pants legs dirty. The so-called pitstop wheels are also great. In the event of a puncture in the tire, it can be removed from the bike very quickly.

As we noticed

  • We would like to emphasize once again the very good ergonomics of a folding bike, which should fit most people. Unfortunately, only the more expensive variants are the G4i and G4i+ that offer height-adjustable handlebars.
  • The LED lighting always turns on automatically while you are driving and turns off automatically again after a period of time when you are standing still. We’d welcome a brightness sensor or manual control.
  • Maximum load (driver and luggage) 100 kg.
  • At the time of testing, several variants of the G4 were sold by the manufacturer.
  • It takes about 3.5 hours to charge an empty battery. It can be changed if necessary. This is not necessary in everyday life, since the bike can be moved to the jack even when folded.
