Moustache Samedi 28 ES vs 28.2: Motor, Seatpost and Lock Differences

The Moustache Samedi 28 ES vs 28.2 choice involves a motor change, a different seatpost entry and an identified frame lock. It is not simply a choice between two battery capacities. The archived UK specifications give both versions a Bosch PowerTube 540 Wh battery and an SR Suntour NVX30 fork with 80 mm travel.

Moustache Samedi 28 ES vs 28.2: compare the motor names

The ES lists Bosch Active Line Plus BDU34, Smart System, with 60 Nm. The 28.2 names Performance Line BDU34, Smart System, with 75 Nm. Keep the complete motor names beside those torque figures: the shared BDU34 text does not erase the separate product labels.

This is a comparison of manufacturer specifications, rather than a hill-climbing test. A larger quoted torque figure cannot tell you how either bicycle will feel on your own route. If you arrange a demonstration, ask for the two named versions so the comparison concerns the equipment you actually shortlisted.

The seatpost wording is different

For ES, the source says Moustache alloy, 31.6 mm diameter and 350 mm length. It does not specify suspension or travel in that entry. The 28.2 explicitly lists a suspension seatpost with 40 mm travel, alongside the same diameter and length figures. Do not turn the ES omission into a confirmed claim that its post is unsuspended.

The Black glossy Samedi 28 ES listing provides a concrete model reference with four frame-size configurations. Use that identity when asking which seatpost belongs to the particular bicycle, especially if a seller describes changes from the original build.

Check the lock separately from the battery

The 28.2 record identifies an ABUS 4650SL frame lock and says the frame and battery locks use the same key. The ES lock field contains a dash. That dash does not document an included lock, but neither does it inspect a used bicycle that may have been equipped later.

Prepare a short comparison note with three lines: motor, seatpost and supplied lock. Keep the common battery and fork below them. This makes the actual differences easier to discuss without assuming that every part changes when the model number rises. The Moustache family introduction explains the wider range; the Moustache topic keeps the model context together.

FAQ: distinguishing the two builds

Does 28.2 mean a larger battery here?

No. Both cited records specify 540 Wh, so battery energy is not the difference established by these sources.

Is the ES seatpost confirmed to have no suspension?

No. Its entry gives material and dimensions without a suspension or travel specification.

Does the ES listing establish an included ABUS lock?

No. The explicit ABUS entry belongs to 28.2; verify what accompanies the individual ES bicycle.
