First look: the new Greyp T5.2 ebike with an MPF 6.0c motor and 700 Wh battery – Back to the future 2.0?

Software and battery specialists Greyp present their new T5.2 ebike. With an MPF 6.0c motor, 700 Wh battery and packed with modern connectivity features, it’s aimed at trekking ebike fans. We took a closer look to find out what it’s capable of.

When Greyp launch a new ebike, it’s like visiting an expo of the future. The Croatian ebike brand is the brainchild of Mate Rimac, who is already causing a sensation in the automotive sector with his electric hypercars, pushing the limits of what can be achieved. With the same unorthodox approach, Greyp are also trying to establish themselves in the ebike sector. The core competencies of the team behind Greyp are software and battery technology, and they create their ebike concepts around that. The latest addition bursting with high-tech features goes by the name of T5.2.

The new Greyp T5.2 in detail

The new T5.2 isn’t Greyp’s first ebike. With the G6, Greyp were able to implement their vision of a high-tech eMTB. With the new T5.2, the Croatian brand is pursuing a similar vision for trekking riders and commuters. It’s an aluminium hardtail with 29″ wheels and a 100 mm travel fork. As with the G6, the 6.0c motor is supplied by Austrian-Taiwanese manufacturer MPF and controlled by Greyp’s custom firmware. Its torque output measures 90 Nm, and it can be updated wirelessly via OTA (over the air) technology. The motor is powered by a 700 Wh battery, which is supplied by Greyp in-house. It’s partially integrated into the down tube and can be removed from the top. The charging socket is on the top of the motor housing in front of the seat tube. Directly above it is a mounting point for a water bottle, which, when used, blocks your access to the charging port. We recommend using a water bottle that doesn’t require a cage, like those from Fidlock, or using the bosses on the underside of the top tube instead. The Greyp T5.2 weighs 26.8 kg in size L and costs € 5,499.

Beware of the hidden camera! The connectivity features of the Greyp T5.2

Apart from the motor, the Greyp T5.2 doesn’t seem particularly unusual at first glance and its hardware doesn’t look that much different from competitors’ ebikes. Only when you dive into the many connectivity features of the Greyp T5.2 does it become clear what makes this ebike so unique. The black and white 3″ display provides a clear overview of all the basic data such as speed, battery level, travel time and distance covered. Looking at it from the bottom, you can see some of the circuitry of the Central Intelligence Module, the Greyp’s on-board computer. Using the Greyp app to link your smartphone to the bike via Wi-Fi, you gain access to lots of additional functions, realising the ebike’s full potential. Like the Bosch SmartphoneHub, the smartphone mount positions your phone over the integrated black and white display. The bracket is cleverly designed to be compatible with almost any phone, with or without a case.

The Greyp app offers two modes, riding mode and remote control mode, dividing its functions between them. In the riding mode, all riding data is displayed on four pages. At the push of a button, the data of every ride can be recorded and evaluated in the activity window afterwards. To scroll through the individual menus, you’ve got to use the thumb joystick on the somewhat crowded handlebar remote, which takes getting used to. The navigation function on the next page is very similar to Google Maps and is just as easy to use. In addition to a schematic map view, you can also switch to a clear satellite image. If you’ve planned a longer route, you can use the Greyp app to display the range of the remaining battery capacity as a radius from your current location. In doing so, the app also takes the selected support level and topography into account. If there’s a lot of climbing along a given route, the estimated range adapts accordingly. Simply select a destination on the map to find out instantly whether the remaining battery level is enough to get you there and back, there but not back, or neither.

Greyp have also tried to embed the social aspect of cycling in both the hard- and software, giving riders more opportunities to share beautiful moments on the bike. There are wide-angle cameras integrated at the front and rear, which are always on while riding. You can save the footage at the push of a button, giving you 30 frames per second of full HD material. All saved videos can be viewed in the gallery of the app. The footage can also be streamed wirelessly to the display of your smartphone while riding, though you should keep your eyes on the road since the image is slightly delayed. The rear-view camera can be used to keep an eye on friends or family behind you. That said, it’s of little use as a rear-view mirror as it doesn’t give you a mirror image. If you get overtaken from the left, the image shows the incoming traffic on the right of the display, as viewed from the camera’s perspective, which can be confusing at some times.

If you don’t want the battery and motor of the Greyp T5.2 to do all the work, you will find a suitable function on the fitness page. Greyp include a wristband with an integrated heart rate monitor that automatically connects to the Greyp app. Once you’ve set a heart rate range as a training zone within the app and you start a training session, the ebike automatically adjusts its support and prompts you to pedal harder when your heart rate falls below the pre-defined training zone.

Off the grid – The connectivity features of the new Greyp T5.2 off the bike

The new Greyp T5.2 is never off the grid. As was the case with its eMTB predecessor, the G6, the T5.2 has a built-in eSIM card and its own internet connection. Does that mean you have to get a data contract for your ebike? Yes and no. Greyp have partnered up with T-Mobile, so data contracts for Greyp bikes are free until December 2025. After that, you will have to sign up yourself if you want to keep using the online functions of the T5.2, which could be worthwhile. On the one hand, you can use it to locate the ebike and, in the event of theft, also shut it down remotely thanks to the so-called kill switch. If you simply want to annoy the brazen thieves from afar, you can also use the remote to lower the support level. When it’s “locked,” the ebike continues recording telemetric data via its sensors. If someone tampers with your ebike, you will receive a notification on your smartphone. You then have the option of having photos sent to you from the ebike’s cameras and can send a warning message to the 3″ display to ward off any would be thieves.

The components of the new Greyp T5.2

Up front, you’ve got a RockShox 35 Gold fork offering 100 mm travel. Braking is taken care of by Formula Cura two-piston brakes, 200/180 mm rotors and an electronic brake light sensor. For the tires, Greyp rely on a pair of fast rolling 29 x 2.25″ Schwalbe G-One models and a mix of SRAM GX and NX components for the gears. The ebike should be suitable for year-round commuting and hauling your luggage with its comprehensive range of everyday accessories. To make your day to day rides a little easier, you get aluminium mudguards, a bike stand and a Busch+Müller lighting system. The rear luggage rack is certified to carry loads up to 25 kg and compatible with the MIK and Ortlieb QL3.1 standards.

The Greyp also appears in the entry-level T5.1 variant for € 4,499. You can purchase a replacement battery for € 649.
