I own a Mantis 10 Pro and an Apollo Phantom. The reason I even own the Mantis is because of multiple let downs by Apollo having great sales success due to their state of the art marketing, but not being able to live up to delivery times and many little quality issues. This is documented here by me and others in other posts here in great detail. In fact i am currently waiting for an Apollo part at the moment and will have been troubleshooting a minor issue with them for over 2 months. They have nice people trying to help, but in the end if you can’t deliver service or have a part in stock…. you have no reliable ride. Ironically I’m a 6 hour drive from their head office and a half hour from their Sales only pop up store.
After close to 1700 kms on the Mantis, I can tell you I have had only two issues, A squeaky stem. and a flat i got last week going home from work. I have fixed that (my first flat) and I am back riding again.
The mantis accelerates faster, is more nimble, lighter to transport by about 10 pounds, and has been super reliable.
The phantom is heavier and has a better folding mechanism and suspension. and looks more futuristic. It’s not a bad scooter concept, it just needs many little improvements and upgrades from when i opened the box last year with it inside. Your city would be a lighter model, I think the 2 × 1000 W motors on the mantis will be a big plus for you as well. My real world driving on mixed settings on my mantis is definitely close to 40 miles To work and back home is a 50 km round trip for me. It easily does that, with power leftover for at least another 30 kms. I don’t get range anxiety on it.
Good luck with making your decision.
