THRON²

The Bosch Performance CX e-drive does have a chain guide interface. However, due to so many different chain guides in the market, you or your dealer have to check the clearance for the specific product you want to use.

Yes, it comes mounted to the bike. If it is damaged or worn out, you can exchange it.

For changing ware parts and components, only use original spare parts. Besides original spare parts, it is allowed to use compatible parts that have been explicitly approved by us. Please ask our customer service.

Probably most panniers will fit. But as there are many manufacturers out there, it is impossible to check all of them. For example, we often use the Ortlieb pannier. That one fits. To be 100% sure, you have to try your favourite pannier directly on your bike or ask your local dealer.

Yes, you can. We even offer EQP versions of the THRON² that are already equipped with fenders, kickstand and rack. We also provide sets of fenders and rack (fender/rack set: AM140122503 / AM130120501) for non-equipped THRON²s that you can order at your dealer. You can use these fenders for most SUNTOUR forks, some RockShox forks and FOX AWL Models that have mounting points. If you want to ride your THRON² with fenders, you eventually have to change your tires as well. The fenders just allow a tire clearance of 55-57 mm. The pannier rack has a 16 kg loading capacity. (8kg per side) As the THRON² is a full suspension bike we advise you to stick to our own rack. As there are many rack models in the market, we cannot guarantee that another one will fit. You can order our rack at your local dealer. The same applies for a kickstand. Your dealer can order it with the number KD145318003 (22 mm screws). For even more details, see the exploded drawing of the THRON² EQP.

Most rear panniers with siderail click systems like QL 2.1 system will fit our custom design rear rack. For example, the Ortlieb Classic und City models fit.

The THRON² is allowed to pull bike trailers that are attached to the thru-axle. This family-friendly update only applies when the respective maximum system weight (rider, co-riders, bike, trailer, equipment) of 150 kg is not exceeded. As there is no test process for the former models, we can not give another statement than no for them.

The THRON² is already equiped with a dropper post.

The cables for the front light are already prepared within your frame. You can ask your local dealer to route them outside and activate the light. For the rear light, a cable needs to be plugged in close to the motor cover. Your dealer has to help you with that one as well.

We collected the commonest Bosch error codes for you:
430: Internal board computer's battery empty - please charge the board computer (via the USB connection of the board computer or inside the mount).
431: Error software version - please restart the system (if the error persists, please get in touch with your FOCUS dealer).
503: Speed sensor missing - please check if the speed sensor is mounted correctly and restart the system (if the error persists, please get in touch with your FOCUS dealer).

We recommend to get updates for your bike. If there is a new firmware, your local dealer can update your bike.

Remove the cover with the lock system, turn key, press button on top of the battery and hold the battery. Be careful that you don't drop the heavy battery.

With sizes M, L and XL, it is possible to switch between the different battery sizes without any problems. In contrast to a change to a 500 Wh battery, a change from the 625 Wh battery to the larger 750 Wh battery is unfortunately not possible in size S, as there is not enough space in the down tube for the larger battery. To do this, you need the horizontal battery in the size you want to change to and you have to screw the faceplate from the old to the new battery (the part where the catch is located). The faceplate looks like this: Picture 1: Battery Faceplate
The guide rail must then be dismantled in order to screw the lower part, on which the discharge connector is located, to the appropriate position. For the correct position, see: Picture 2: Battery
Here are the steps in summary once again: - Remove battery cover - Remove battery - Mount faceplate of e.g. 750 Wh battery on 625Wh battery; see picture 1 - Loosen guiderail (4 screws) - Disconnect battery cable and charging port connector - Remove guiderail - Move the discharge connector/battery holder to the desired position; see picture 2. - Reassemble the whole unit in reverse order. It is recommended that this is always carried out by a FOCUS dealer.

There is no definite answer to that. Different factors have an impact on your range: Your weight, your luggage, the terrain you ride, which support mode you prefer and and even the temperature influence how long your battery will last. There is a range assistant by Bosch that can give you an idea: Bosch range assistant

We don’t offer a second battery for our THRON².

No, that's not possible and even if it would, we do not recommend it.

Only a few steps need to be taken. Remove the battery, pull off the display and put the cover back on - done.

For changing ware parts and components, only use original spare parts. Besides original spare parts, it is allowed to use compatible parts that have been explicitly approved by us. Please ask our customer service.

The maximum seat post insertion depends on your frame size: S: 200 mm; M: 230 mm; L: 260 mm; XL: 290 mm

Of course all groupsets that we offer in the different specs do fit: Shimano XT, SLX or DEORE and a SRAM SX Eagle. All are equipped with a 12-speed drive.

You can use a maximum rotor dimension of 200 mm.

For our 29" wheels it is 2.6" or 66 mm

29" wheels.

The total weight limit of THRON² is 150 kg. This limit includes the whole system weight of bike, rider and all equipment. To be sure, you can find the total weight limit on the CE sticker of your bike.

1by and 2by means that the bike is either equipped with two or only one chainring in the front. As the Bosch mid motor just allows one chainring, our THRON² is 1by only and it is not possible to change to 2by.

If you want to change your fork, the one you choose has to be "e-bike ready" and approved by the manufacturer. The travel must be 100 mm. In case you are in doubt, ask your local dealer.

Our advice is to use the specced shock because we optimised it for the F.O.L.D. chassis and the bike's geometry. If you still want to change, you should speak to your local dealer and try if another one fits. As there are many shock models in the market, we cannot guarantee that another will one will work.

SAG is the amount of way the shock compresses when you just sit on your bike without moving. You adjust it with the pressure you pump in your shock with a shock pump. We recommend 30 %. To see the actual percentage, you use the O-Ring that is placed on the fork and shock.

Replacement batteries and chargers for our bikes with BOSCH motors can be purchased through your FOCUS dealer at BOSCH.
