Yes, There is a flip chip that can be used for setting up a BB position based on rear wheel size set up; as a mullet 27.5/29” or a full 29”. When the flip chip is in the high position, the bottom bracket height becomes higher; it improves pedaling clearance, enabling riders to pedal through rocky and rooty terrain and vice versa.

The bike comes with a 210mm x 55mm twin eyelet shock, you are able to change the shock with the same size. However, it’s worth noting that Polygon has a specific tune on their stock rear shocks to work best with the specific bike platform, If looking to replace the shock make sure to have the damper and spring setting tuned for the platform for optimized performance.

The standard forks are 150mm travel, but you can run up to 160mm travel single-crown fork if you like. It is not tested to withstand the forces of a dual crown fork.

For sure. In fact, the Siskiu TE comes equipped with a Shimano chain guide mounting to the drive unit.

The bike comes fitted with 203 mm rotors. You can run up to 203mm rotor on the rear and 220 on the front. The minimum size you can go is 180mm. The bike comes standard with 200mm both front and rear.

Shimano STEPS e-MTB drive systems provide 4 power modes; Eco, Trail, Boost and Walk-Assist; and its E-TUBE PROJECT app lets you customize the assistance of each mode to your personal preferences.
We recommend only shifting one gear at a time (up or down the cassette) and try to back off the power through the cranks a little as the integrated torque sensor will immediately react and also back off the motor’s power. Trail mode is much more intuitive with this than Boost mode. We recommend saving Boost mode for cranking straight-up big climbs where gear shifting is limited.

Insert a 4mm Allen key into the hole above the battery cover on the underside of the downtube. Rotate it in the direction depicted by the arrow to release the battery lock. This will allow the battery to hang slightly down from the tube, creating access to the battery release lever at the top of the battery. Be sure to use two hands when releasing the battery as it’s quite heavy and shouldn’t be dropped.

Ensure the battery connections are clean and dry. Install the base of the battery into the lower mount closest to the motor, then press the top of the battery into the downtube until you hear and feel a “click”. Then your battery is installed.

The battery can be charged either installed in the bike, via the charging port on the left side in front of the motor, or detached from the bike using the additional connection port supplied with the charger.

Yes. The SHIMANO STEPS systems are waterproof for use under normal riding conditions, including heavy rain. Please do not use a high pressure washer to clean your bike.

When gravity is on your side, there is no limiting your speed beyond that of a “normal” MTB with 160mm of awesome suspension. As far as motor assistance is concerned, the Shimano STEPS systems will provide motor assistance up to 20mph (32km/h) in the USA and Indonesia, or 25km/h in Europe and Australia.

The range of any e-MTB depends on many variables, including terrain, gradients, rider weight, assistance mode, rider input, ambient temperature, etc. While 100km adventures are definitely achievable aboard the Collosus N8e, we recommend using the range overview on the display for the best estimate. The range overview is recalculated continuously by calculating speed, rider behavior, and power consumption. This means that range overview makes a prediction, which can vary depending on these different factors.

Stay tuned on our website and social media, we will announce further for the availability.

The bikes are supplied with Shimano’s E-bike system. The T7E is supplied with Shimano BT-8036 630Wh whereas the T6E is supplied with the lower BT-E8035 504Wh. The T6E will fit a larger battery capacity, the same as the T7E (BT-8036 630Wh)

Yes. Shimano approved front lights can be connected to ports in the STEPS drive unit (motor). This requires significant internal routing and e-system component removal so we recommend having this upgrade made by a certified Shimano STEPS workshop.

W013 is likely the most common error for first time STEPS users. Officially, W013 means Initialization of torque sensor not completed successfully. Don’t fret. It typically occurs when the system is turned on while a load is applied to the crankset. Try turning the system off, ensuring your foot is not on a pedal and the cranks or pedals are not leaning on the ground or against a wall; then turn the system back on again. This should solve the issue.
If you still see the issue try a 'hard reset' - press the power button for 12 seconds and power on once again.
If W013 or any other error code persists, contact your place of purchase or a certified Shimano STEPS workshop.

While Shimano’s drivetrains offer very smooth shifting even under the load, we recommend only shifting one gear at a time (up or down the cassette) and try to back off the power through the cranks a little as the integrated torque sensor will immediately react and also back off the motor’s power. Trail mode is much more intuitive with this than Boost mode. We recommend saving Boost mode for cranking straight up big climbs where gear shifting is limited.
