Cons

- Range shorter than expected
- Assembly and setup take effort
Questions and answers
- Which is better for commuting?
- The SYX MOTO suits short commutes better: it is cheaper, has a 48V system and a certified battery. The A20 is faster but heavier, which matters if you carry it up stairs.
- Which has more power?
- The Aostirmotor A20, with a 500W motor and a 25 mph top speed against the SYX MOTO's 350W and 20 mph.
- Is the A20 worth the extra $51?
- Yes if you want the extra 150W and 5 mph. No if you mainly ride flat city streets, where the SYX MOTO's 48V battery and lower price win.
- Which is easier to carry folded?
- The SYX MOTO, most likely. The A20 is about 70 lbs, and SYX MOTO does not publish a weight, but its aluminum frame and smaller motor point to a lighter bike.
- Do both have fat tires?
- Yes. Both use 20" x 4.0" fat tires and front suspension, so rough pavement and light trails are fine on either.
- Which has the better battery?
- The SYX MOTO's is 48V and UL2849-certified, which is the safer pick. The A20's 36V 13Ah pack has more watt-hours on paper but a lower voltage.
