Quick plug-and-play installation. No setup!

• Compatible with the latest Bosch 2021 FW upgrade (increased torque to 85NM) Compatible with all BOSCH engines (2013 – 2022) such as Active Line, Active Line Plus, Performance Line, Performance CX Line, including motors of the 4th generation (MY2022) with anti-tuning software. Attention: NOT COMPATIBLE with the 2022 (new smart system) BES3.
  
  

• The VOLspeed V4 Bosch is the latest generation of this popular tuning chip. The casing of the module is even more robust and comes with extra functions. Now even more robust and with a greater range of functions than ever before. VOLspeed V4 is not only compatible with most previous Bosch E Bike engines, but also with the new Bosch 2022 (Gen 4) drive systems. 

• The VOLspeed tuning kits are one of the most popular e-bike tuning devices on the market. Their popularity is due to their unique engine optimisation feature that allows to reduce the annoying ‘wall effect’ of the engine when reaching maximum speed. This tuning dongle completely unlocks your engine to 28mph (45km/h). Another appealing feature is that the speed limit can be adjusted for reduced battery consumption. With the tuning active all data on the display remains accurate. 

• The tuning hardware is completely encapsulated and protected by a rigid casing which guarantees for toughness, impermeability, and thus hardware longevity. The VOLspeed is manufactured in Germany.

For every ebike rider - YOU control the speed of your ride, not someone else!

Volspeed fits all Bosch E-Bike drive systems from the model year 2014 onwards:

• Active Line
• Active Line Plus
• Performance line
• CX Line
• Also compatible with the new Bosch 2020 E-Bike drive systems, for example, Performance CX 2020 (Gen. 4)
• Only “Bosch Classic” engines, the model year 2013 or older, are not supported.
• The VOLspeed V3 tuning module is compatible with the following display types: Intuvia, Purion, Nyon, Kiox.
• Note on COBI.bike: If you plan to convert your E-Bike display to COBI (or have already done so), the operation of the module will change. Also, if you are using COBI, it is not possible to set an individual activation code.

NOTE: IT WILL NOT WORK WITH THE LATEST 2022 BOSCH SMART SYSTEM.

Main differences between the V3 and the V4:

• Volspeed V4 has an easier and faster plug-n-play installation (no setup required)
• New speed limit of 28 mph (45 km/h) on V4, where V3 has unlimited speed (more prone to errors, however, they are extremely rare)
• Volspeed v4 is fitted with much more error-proof engineering.

Volspeed is manufactured and designed in Germany and is compatible with all 2014-2021 Bosch e-bike motors (4gen / 3gen / 2gen).

The main feature of the tuning kit is removal of 16mph / 25km/h speed limiter. After the tuning kit is installed the e-bike shows actual speed on the speedometer, and also upgrades to the new 28 mph (45 km/h) speed limit.

• This tuning kit is compatible with all Bosch motors starting 2014-2021 (4gen / 3gen / 2gen). 

• Works with all brands and types of ebikes (Cube, Focus, Haibike etc) including all Active Line, Active Line Plus, Performance Line and Performance Line CX models including motors of the 4th generation. 

• DOES NOT WORK WITH 2022 BOSCH SMART SYSTEM

Is warranty safe with  Volspeed?

Yes, Volspeed is undetectable by dealer, but using Volspeed  may void your warranty if you service the bike with tuning kit installed. We highly recommend removing Volspeed before servicing your e-bike at your local dealer.

Is it safe to use on motor and battery?

Yes. E-bike motors were designed to be derestricted, the speed limits are in place due to legislation, not safety of the motor. They are safe to use.

Will travel range drop after installing tuning kit?

It depends on your riding alone. If you pedal over regular 16mph restricted speed - the motor will use more power and more battery. Our experience shows around 10% decreased range, but 90% more fun in the remaining range.

Will the Volspeed work with Bosch 85Nm update (2020 Gen4 Bosch Motors) ?

Yes, it works better because after the latest update the oversensitive anti-tuning software from Bosch was tweaked and made less sensitive, which means no more 504 error. 

What about 504 error code with Bosch Gen4 Motor?

Before updating latest Gen4 motors (from 75Nm to 85Nm) the anti-tuning of Bosch was so sensitive that sometimes 504 error (anti-tuning error) popped-up without volspeed installed. If your bike doesn't have the 2020-06 85Nm update we'd recommend installing Volspeed tuning kit. If the ebike has the update the Volspeed will work perfect. 

What happens if you get 504 error code? Is it bad?

It's not the end of the world. All you have to do is remove the Volspeed and ride without it for 20 minutes. The error will reset and you will be able to install the Volspeed again. We do recommend riding without a tuning kit at least 20 miles (30km) or 60-90 minutes  before installing the tuning kit back, fully resetting the system. 3 times of 504 means you will have to take the bike to the dealer to reset it. These are extremely rare cases of 504 error, especially with 85Nm update.

Is crank-puller needed to install the Volspeed?

Depends on your motor. Gen4 motors usually are easily accessable without removing the crank. Gen3 (2016-2018) motors usually require a crank puller. You can choose to add a crank puller next to 'ADD TO CART' button.

Note software updates

We generally advise against software updates for the Bosch drive system after installing a tuning module. It cannot be guaranteed that the tuning module will also be compatible with future software versions of the drive system, so please update only if neccessary and approved beforehand with us.

Note COBI.bike / SmartphoneHub

If you use the tuning together with a COBI.bike or SmartphoneHub, the operation changes. We have summarised the

underlay in the following instructions: COBI instructions manual By the way, an individual activation code cannot be used when using COBI or SmartphoneHub!

• Individual activation code to prevent unauthorized riders to activate the tuning. 

• Completely derestrict the engine for speed up to 28mph (45 km/h).

• Set your own speed limit to adjust or reduce battery consumption.

• All settings can be easily made using the display control buttons.

• The tuning is always switched off after switching on the bike.

• Correct total mileage of the bike even after removing the tuning module, as the kilometers are tracked in the engine control by the tuning module.

• Range calculation remains accurate even with the tuning active.

• Set a ‘softer control behavior’ (dynamic mode) which reduces the annoying engine abrupt cut-off. This allows for a more pleasant driving experience and a constant pedal stroke. 

• Battery percentage remains accurate even with the tuning activated. In active mode the battery range is calculated as: Interval: 4 second range, 1 second battery level.

• Workshop mode: Deactivate the module completely, e.g. if a workshop visit is due.

• The module is around 40 percent smaller than in the previous models for a better fit into the engine compartment. 

• The electronics are completely encapsulated in the housing, making them absolutely waterproof.

• Does not require any diagnostic tool for installation. 

• Works in conjunction with Pow Unity Biketrax GPS tracker.

The tuning it removes the speed limitation of your engine and does not increase the engine power output. It simply removes the speed limiter which cuts the assistance over 16mph (25km/h). What is does is keep the motor assist on until you can no longer pedal any faster due to limitations of bike gearing or leg-work. With the tuning active it is hard to determine the battery consumption since there are many factors involved such as riding style, terrain, cadence, and etc. As a role of thumb, expect the battery drainage to be in the +/-10% range.

Anti-tuning errors are also triggered by other factors and may not be directly attributed to anti-tuning measures. These errors do happen even though no tuning kits are installed.

ERROR CODE 504

The infamous Error code 504 is an anti-tuning algorithm that is triggered when certain riding parameters are exceeded (anti-tuning measures). The algorithm relies on data collected from the engine software such as speed, cadence, battery consumption, and other engine parameters to determine if the engine has been derestricted. 

These error codes are very rare, but they do sometimes happen.

According to tuning manufacturers error 504 has been triggered on only 1.5 % of the Bosch engines. In case the error 504 is triggered, we strongly advise to remove the tuning and to ride the bike for 20 miles (30km) or so (30-60 minutes ride is usually enough)  without the tuning installed. This will allow the bike to clear the 504 error code and reset the engine to pre-code conditions. To avoid the error to occur again we suggest to reinstall the tuning and reset the max speed to 28 mph (45km/h) since no error 504 code has been reported above the 28mph (45 km/h). 

NOTE: It is not uncommon for the 504 error to also appear on standard bikes that have never been derestricted before. 

GEN 4:

1.0.2.0: Bug in motor firmware can cause an error 504 (confirmed by Bosch, update recommended) Please note that before updating your motor you must uninstall the tuning kit and install it again after update.

1.0.3.0: No errors were reported so far. This update was to fix the 504 problem.

1.1.0.0 & 1.1.2.0: Some customers had reported an error 504. It seems that the error only occurs when a speed limit of 28 mph  (45km/h) or higher is set. Since Volspeed V4 maximum speed is limited to 28 mph - you don't need to do anything to prevent the error.

GEN 3:

up to 1.2.3.0: no problems so far

1.3.0.0  Some customers had reported an error 504. It seems that the error only occurs when a speed limit of 28 mph  (45km/h) or higher is set. Since Volspeed V4 maximum speed is limited to 28 mph - you don't need to do anything to prevent the error.

GEN 2:

No error code 504 have been reported so far. 

There is also some more reasons for a 504 error:
- defective bearings inside the motor
- a defective free hub inside the motor
- high mechanical noise from the motor
- misaligned speed sensor magnet
- crashes with the bike

FIRMWARE UPDATES AND DERESTRICTED ENGINES

Engine manufacturers are constantly working on improving their engines. They do have access to a large database of information as data is transmitted to the manufacturer each time an engine is hooked into the dealership diagnostic tool.
This data allow the manufacturers to have a better understanding on how the engine behaves/ perform under a wide range of circumstances.
Through FW updates the manufacturer is able to improve several aspect of the engine such as performance, power delivery, battery consumption and management, to smooth the engine engagement/disengagement, and to correct other parameters.

Note that before updating software of the e-bike it is best to uninstall the tuning kit.
 
SOFTWARE UPDATES

We strongly advise NOT to perform any Firmware updates until there is approval from Volspeed that the update is safe to use with your tuning kit.

It is for this reason that we strongly advise NOT to perform any Firmware updates until there is proof of safe usage.

OTHER ERROR CODES (503) 

If 503 error occurs, please check the connectors of the tuning kit if they are not loose. Please reconnect them.

If this does not help, please check speed sensor errors, which can also occur when the magnet is misaligned with the speed sensor on the rear wheel, or due to a damaged rear sensor itself.
