Is 85 Nm of torque realistic for this bike?

85 Nm is a high figure for a hub or budget mid-drive motor, and marketplace listings often quote peak rather than sustained output. Treat it as a claim until independent testing confirms it.

Can I get parts and warranty service?

There is no dealer network behind the Temu name, so warranty claims and spare parts go through the seller. Check the stated warranty terms and whether batteries and controllers are sold separately before buying.

Is it good for real mountain trails?

It is better suited to light trails, fire roads and commuting than to technical descents. Frame strength, brakes and suspension on budget e-MTBs are usually the limiting factors.

Does it come assembled?

Budget marketplace e-bikes typically arrive mostly assembled and need the front wheel, handlebars, pedals and sometimes brakes fitted and checked. Budget for a shop safety check if you are not confident.

How does it compare with a name-brand e-MTB?

It offers more claimed power and torque for the money, but name brands bring proven frames, better components and real warranty support. The trade-off is capability and backup versus headline specs.
