All SAM² are equipped with the 40 mm C.I.S. 2.0 stem.

The FOCUS SAM² already has an integrated chain guide.

You can find this information per size in the specs under ‘seatpost’. The drop differs depending on the seatpost fitted.

Yes, all our FOCUS SAM² models are specced with a dropper post. The dimensions are: 34,9 mm diameter and a maximum insertion depth per size: S: 220 mm; M: 250 mm; L: 270 mm; XL: 290 mm.

Yes, both the in-house post moderne dropper post and the oneUp V3 dropper post can be reduced in travel using the spacers included in the scope of delivery.

Yes, both is possible.

The SAM² uses the ACROS ZS56/ZS66 angle-adjustable headset with integrated cable routing. Please note that you need to use a different headset depending on the frame size. You can find the right model for your bike in the Acros headset finder.

You can order a different stem length via your dealer. All cables run directly into the frame below the stem, so you don’t have to open brake lines or shifting cables when changing the stem. But you should consider the following: Switching to a longer stem might require longer cables. Make sure the cables are long enough. Switching to a shorter stem might lead to long cables which could be shortened for a cleaner look. Here are all stem lengths with their order number:
Art. No. 250002700 C.I.S. 2.0 stem 50 mm lang
Art. No. 250002600 C.I.S. 2.0 stem 40 mm lang

Yes, you can shorten the handlebars of the FOCUS SAM². All handlebars have markings for different widths.

Judging a damage from the outside or based on a picture is almost impossible. In case of damage, you should visit your FOCUS dealer.

Replacement batteries and chargers for our bikes with BOSCH motors can be purchased through your FOCUS dealer at BOSCH. Pay attention to compatibility with the BOSCH Smart System

Battery: BOSCH PowerTube 600/800
Charger: BOSCH Standard (Smart System)

Yes, the FOCUS SAM² is available with both the compact 600 Wh battery and the larger 800 Wh battery. Both are removable and differ only in appearance, with the larger cover for the down tube. The only exception is the SAM² 6.0, which is only sold with the 600 Wh battery. However, the 800 Wh battery can also be retrofitted here. Ask your local FOCUS dealer for more information. What's more, the FOCUS SAM² is compatible with the 250 Wh range extender in all sizes. That means four battery configurations, ranging from 600 to a whopping 1050 Wh.

Other than the new battery of course, you only need the fitting down tube cover (600 Wh: Art.No. 998929000; 800 Wh: Art.No. 998930000). Please contact your local dealer about this.

Yes, you can control all functions of the Smart System with the e-Bike Flow app and also customise ride modes to your liking.
See Bosch Flow App for more information.

No, that's not possible.

We recommend getting updates for your bike. If there is a new firmware, you can update your e-bike firmware via the Bosch e-Bike Flow app or ask your local dealer.

Remove the cover with the locking system, turn the key, press the button on the top of the battery and hold the battery. Be careful not to drop the heavy battery.

There is no definite answer to that. Different factors have an impact on your range. Your weight, riding type, the terrain you ride, which support mode you prefer and and even the temperatures can influence how long your battery will last. Use the Bosch website beforehand to make an educated guess which battery size fits you best: Bosch range assistant
Or you check out different scenarios here: Bosch Performance CX
When you buy it, make sure you get the right battery size or ask your local dealer for help if you are not sure if 600 Wh or 800 Wh is the best battery size for you. Keep in mind that the FOCUS SAM² offers full exchangeability between those two battery sizes and is compatible with the 250 Wh range extender for all sizes.

For changing wear 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. If you are in doubt, please contact your local FOCUS dealer or ask our customer service.

No. If you want the full tracking compatibility and the perfect digital experience take a look at the THRON² MY25 .

In the case of error message F10004, the software version of your e-bike does not match that of your Range Extender. You can fix this by updating via the Bosch Flow app. The range extender must be connected to your e-bike for this. Alternatively, you can also go to your FOCUS dealer who can install the update for you.

The headset is sized for forks with 1 1/8" - 1,8" steerer. The travel must be 170 mm. Also check all other standards like post mount, axle dimensions, etc., if you want to change your fork. Additionally, the one you choose has to be approved for 150 kg system weight by the manufacturer. If you are in doubt, please contact your local FOCUS dealer.

You can use a maximum rotor dimension of 225 mm.

The maximum insertion depth of the seat post in the frame depends on your frame size: S: 220 mm; M: 250 mm; L: 270 mm; XL: 290 mm.

The total weight limit is 150 kg for the FOCUS SAM². It includes the weight of the bike, the rider and all equipment.

Maximum tire width is 2,6 or 66 mm.

The SAM² is equipped with mullet wheels, i.e. a 29‘ front wheel and a 27.5’ rear wheel. Since the whole bike has been optimised for this concept, we strongly recommend that you do not change this.

The largest chainring you can use has 36 teeth, the biggest cassette up to 52 teeth.

Please see the exploded drawing for all details:
FOCUS SAM² MY25

The SAM² has a 55 mm chain line.

Yes, the FOCUS SAM² is approved for the attachment of a bicycle trailer. Please note the authorised total weight of 150 kg.

The FOCUS SAM² has threading and a frame bag. The bag is included with sizes M, L and XL and fits. The frame size S has threading but our FOCUS frame bag does not fit. However, other bags that can be screwed on could work.

An Apple Airtag or Chipolo Gen. 2 can be placed in the down tube under the battery. To do this, two cable clips must be pushed together to attach the Airtag or Chipolo. Then the cable clips must be pulled together with two cable ties to clamp the Airtag or Chipolo. The whole thing is then hidden and locked by the reinserted and closed battery.

All parts required for changing the display or mounting a GoPro are included. All spacers for reducing the suspension travel of the dropper post are also included.

Our advice is to use the specced fork because we optimised it for the bike's kinematics and its use case. If you want to change your fork, the one you choose has to be approved for 150 kg system weight by the manufacturer. The headset is sized for fork steerer with 1 1/8" - 1,8". Please check the steerer dimensions of your new fork and choose the matching base plate. You can get the matching base plate by our dealer. The travel must be 170 mm. Also check all other standards like post mount, axle dimensions, etc. In case you are in doubt, ask your local FOCUS dealer.

Our advice is to use the specced shock because we optimised it for the bike's kinematics and its use case. If you still want to change it, you should speak to your local FOCUS dealer and try if another one fits. As there are many shock models in the market, we cannot guarantee that another one will work. The shock dimensions are 230 x 62,5 mm // 25 x 8 / no bushing.

The FOCUS SAM² has 170 mm of travel at the fork and 160 mm at the rear triangle.

The spring rate is different for each size. You can find this information for each size in the specs under ‘Damper’.

Yes, if you want to customise the SAM² to your individual requirements, you will get your money's worth. Thanks to headset cups and FLIP CHIP in the rear triangle, various geometry combinations are available and easy to customise.
With the headset cups, the steering angle can be varied between 63.5° and 64.5°: the flatter the more stable and the steeper the more agile is the simple formula. This allows you to adjust the steering angle to suit your riding style and the terrain. Particularly good: this also works with the fully integrated cables without any hassle and without hours of fiddling.
With the FLIP CHIP in the rear triangle, you can choose between 441 or 448 mm chainstays to tune the balance of the SAM². Rugged or stable – you decide! Both settings work with the same number of chain links.
We recommend the short setting with 441 mm for frame sizes S and M and the long chainstays with 448 mm for L and XL, but ultimately the decision is yours. Trying out is expressly encouraged! The difference, especially in cornering, is enormous.

Yes, it is possible to remove the spacers. Our integrated spacers, which the cables run through, are divisible. This means you don't have to open any cables. If you don't want to saw off your steerer tube directly, you can build round spacers on top of the stem. We recommend a round top cap in this combination.

The FOCUS SAM² applies to condition 5: Enduro & Downhill bikes.
