Here is my experience so far with the M2 Pro.

For starters, i'm a big guy. 6ft 4, 470 lbs but still very active and desperate for some wheels that could hold up to my mass. That's when I found the M2 Pro.

I was cautiously optimistic about the bike when I purchased it and waited over a month to receive it. On the maiden voyage I noticed a few things i didn't like but were not deal breakers:

1. The seat post/seat clamp is pure trash. Buy a new one or deal with stripped out teeth and a wonky seat

2. The bike is BIG and not very agile

3. The brakes are not as good as you'd like but fair enough with almost 600lbs rolling.
4. It tops out at 20mph (fixable through the screen options)
5. It squeaks and creeks ALOT (very loud)

I got home and ordered a new solid bracket seat post and new seat (bigger) and am very pleased with the results.

After getting the hang of the bike it becomes easier to steer and a little more agile as your ability to control it improves.

Easy 60 second fix to get the speed limiter removed

To fix the squeaks and creeks I liberally applied WD 40 to the front rear suspension bracket and spring and adjusted the bolts there (problem solved)

After fixing these issues I rode a good 200 miles before noticing any further issues.

After about 200 miles I hit my first major issue:

All \~8 bolts holding the motor to the rest of the hub assembly all backed themselves out and were completely gone. I only noticed when i heard a huge clunk/grind when the last poor bastard bolt gave way and the hub separated into 2 pieces. I found a few bolts and put it back together for the mean time but Aipas is sending me a new one for warranty to fix this issue since some of the bolt holes in the motor/hub are stripped out badly.

This was very disappointing but i'm very happy with Aipas for making it right and sending a whole new rear wheel assembly (including tire and tube etc).

I have cautiously ridden a few times since (though missing 3 stripped out bolds in the rear hub,) i'm confident the 5 remaining with loctite will be fine as they are fairly evenly spaced and the hub is solid ( just take it easy when riding).

Not major issues since this but I have mixed feelings about this bike.

1. It's amazing that it's so massive and can handle my weight really well (30mph fairly easy)

2 It's fast and feels solid

3 I get about 12-17 miles out of a full charge depending on how much i peddle and how fast I go

4 The light is SUPER bright and I love this.

1. I'm upset with Aipas for misleading early buyers with lies about Samsung 21700 batteries and the Beifong motor lie

6 I'm happy with Aipas for holding up every bit of their end on promises of warranty, and free parts for waiting so long

7 For $1k this bike is amazing

8 for being a massive human being this bike handles my abuse surprisingly well (I ride fast and hard most of the time, racing cars and riding fast on grass and dirt and cornering hard etc)

9 This bike is heavy and hard to handle while walking even for a big guy

10 The key port for the battery at some point shifted and is off center to the hole which is odd

11 I got flat tires within the first 20 miles on front and rear because the tires are paper thin (i've since upgraded to thick inner tube liners, thick tubes, and self sealing goop and have been flat free for 180+ miles

12 make sure to tighten and retighten EVERYTHING on this bike. Everything loosens over time on this bike including the steering and motor hub lol.

1. I with it had more gear range to play with, i feel very limited with only 1 gear in the front. Overall, there is no other bike on the market that can do what this bike can do for the price. I'm filled with mixed feelings but the overall sentiment is this bike is really great.
