I have done a video check that out if you want more details on the new bosch system but these use the 625 watt hour Bosch into battery so you get around 25% extra on top of the 500 watt hour batteries in terms of range or battery life and personally to me that makes quite a big difference because if you're out for all-day adventures.

The 250 W motor may seem a little on the small side but it’s quite capable. It gives a top speed of almost 16 mph without any form of pedalling. The acceleration is decent, aided by the low weight of the bike. However, it can’t really compete with bikes that have 500 W or higher motors. These do tend to cost more than the $1000 mark though. The battery is said to give it about 30 miles maximum range when in assistive mode. The battery is able to fully charge in 4-6 hours.
The build quality, however, is generally fantastic. It feels sturdy and strong, the clip to hold the fold in place never feels like it’s coming loose and the wheels feel like they can conquer anything. Also the suspension system is quite impressive and isn’t even included on the non-folding Ancheer Electric Mountain Bike. This suspension system and the strong frame help give the Ancheer the ability to comfortably hold riders who weigh up to 150kg (330 lbs).
The fit is a little rough for me. I'm tall, about 73 inches, and I feel like the bike is small. I've ridden a few dozen miles to include a trip with a kids trailer towed behind, and it hasn't been really uncomfortable, but a little cramped compared to my Schwinn Trailway 28"/700c hybrid bike. Seat adjusts up but feels tilted back a little more than I would like. I have ridden in shorts and tshirt to the beach as well as khakis and a button up with backpack to work, ok comfort both ways. Perhaps it will just take some time to get used to.
