Everything you need to know about FIT (Panasonic)
FIT e-bike system integration
Because it’s all about enjoying the ride
Whether you're looking for a mountain e-bike or a city bike, FIT offers a wide range of batteries, motors, displays and digital functions. The perfectly coordinated system integration of FIT – FLYER Intelligent Technology – combines components and functions from the best manufacturers in one e-bike, including for our FLYER e-bikes. The aim is to make it as easy and safe as possible for the user, thus guaranteeing maximum riding enjoyment.
All FLYER e-bikes with FIT e-bike system integration
1. FIT e-bike system integration
Individually combined
Our FLYER e-bikes are equipped with FIT technology, among other things. Thanks to the open bus system and the plug-and-play function, numerous combinations and extensions of individual components (motors, batteries and displays) are possible. So nothing stands in the way of a unique riding experience.
Smart connections
Digital solutions such as the FIT E-Bike Control app and the Drive Screen increase riding comfort and provide additional safety. This makes it possible to adjust the e-bike even better to the rider.
Intelligent configurations
All of the FLYER e-bike’s electronic components can be locked using the FIT Digital Key, while the Long Life Mode extends the lifetime of the battery – and the Boost Function provides an extra boost of energy when things need to be done quickly.
2. Motors
The motor is at the heart of every e-drive unit – and it’s what turns a classic bicycle into an e-bike in the first place.
We install the following Panasonic motors in our FLYER e-bikes:
- Panasonic GX Power Plus: Particularly quiet yet powerful drive with a wide range of applications.
- Panasonic GX Ultimate: The high-end drive from Panasonic. Very light, pleasantly quiet and with record levels of assistance.
- Panasonic GX Ultimate Pro FIT: The tried-and-tested GX Ultimate, now with FIT 2.0 motor control and even more power (+ 5 Nm). “With the powerful Panasonic GX Ultimate Pro FIT, no incline is too steep. 95 Nm of pure power!”
Thanks to individually configurable assistance levels, the motor (in %) always increases your own performance just as much as you want:
- ECO (70%)
- Standard (150%)
- HIGH (300%)
- AUTO (70-300 %): Intelligent automatic assistance level detects at all times how much motor power is required.
Motors with FIT Inside produce a natural riding experience. FIT Inside highlights the harmonious coordination between the motor, the system software and the sensors. High-quality components are thus combined into a harmonious complete system. In other words, this makes every ride on the FLYER e-bike incomparable.

3. FIT e-bike batteries
With their high-capacity batteries, FLYER e-bikes with FIT are champions of both range and altitude. All FLYER e-bikes are fitted with high-performance batteries that contain cell types that have been specially developed for use in e-bikes. They boast a perfect balance between capacity, performance, weight and lifespan. The special feature of lithium-ion batteries is their particularly high energy density. This means that they can store more energy and are relatively low in weight.
FIT batteries are equipped with the latest generation of lithium-ion cells, and the intelligent battery management system protects the battery against overloading and errors.
Best battery handling
All batteries installed in FLYER e-bikes have excellent battery handling. They are easy to remove and can be charged either directly via the e-bike’s charging port or away from the bike.
The Long Life Mode significantly extends the battery’s lifespan using gentle charging. This additional function can be easily adjusted via the Display or in the menu of the FIT E-Bike Control app. This means that the battery charges at a lower charging current and maintains a 20-80% state of charge.
Still not enough range? Then we recommend adding the FIT range extender (not suitable for every model) or following our tips to increase your range.

4. FIT displays – everything in view
Optimum legibility
The scratch-resistant color displays feature a large font and are therefore easy to read – even in direct sunlight or with polarized sunglasses and when riding at night.
Display readouts:
- Riding modes and speed displays (max., average)
- Charging status and range
- Route information (incline, total elevation gain, kilometers, ride time)
- Fitness/performance indicators (watt, pedal cadence, heart rate, calories burned)
- Warnings (black ice or service)

Combined with the FIT E-Bike Control app, this makes it easy and convenient to plan your next tour simply and record it if necessary. In conjunction with the Komoot app, recorded tours are available in the FIT E-Bike Control app, enabling navigation via the e-bike’s display.
The following displays have the FIT 2.0 functions*:
The scratch-resistant color display offers optimum legibility throughout the journey and, in addition to the standard functions, also offers access to other functions such as navigation, heart rate monitoring and more.
Attachment:
The display is easy to attach and remove at any time using the matching bracket. The display can also be attached permanently.

The small compact display has a high-resolution 2" colour screen and is therefore particularly handy. Standard functions such as time, charge level display, range display, kilometre reading and light control are available.
Mounting:
The display can be easily attached and removed at any time thanks to the matching holder. The display can also be permanently mounted.

The FIT drive screen turns your smart phone into a fully-fledged display with access to all riding data. But that’s not all: it also offers detailed navigation and route planning with range forecasting (Geo Range). The menu can be controlled via smartphone or the e-bike’s control panel.
To do this, simply connect the e-bike to the FIT E-Bike Control app and activate the function as a lifetime version or annual license via in-app purchase.

*Important: The previous year’s FIT D0 and FIT D1 models are equipped with the FIT 1.0 system function and do not yet have all the display options listed above for the FIT 2.0 system function. E-bikes with FIT 1.0 system integration displays cannot be retrofitted to FIT 2.0 or replaced with new displays.
5. Controls
The ergonomic and elegant FIT Remote Basic control element makes it easy to access and control all riding and performance information at any time.
The buttons are backlit and have vibration feedback that intensifies with increasing speed. This makes it safe and intuitive to use, even when wearing gloves or in the dark, without having to take your hand off the handlebar.

- Short-term boost function for maximum performance: Ideal on steep sections or when starting off on busy roads, the extra thrust with short-term maximum assistance guarantees maximum riding enjoyment!

About Biketec GmbH
FIT was developed by FLYER AG, the Swiss e-bike pioneer, and was first launched onto the market with the FLYER U Series in 2015. The aim was to synchronize the software and hardware of an e-bike in the best possible way and to integrate new functions. To combine our expertise in FIT technology and provide access for other e-bike manufacturers, we set up Biketec GmbH on July 1, 2020, based in Huttwil, Switzerland.
