Intelligent Alarm Brake Lock

I found it easy to use, I don't know how long the batteries last but on most power repaired stuff. The batteries usually last quite a while.

Havent used it as of now.

Quick to
Apply. Quick to release . I do not use a chain or leash with it. I just put it on brake roder. And Im not away from trike long. So it fits for me in my area.

Left brake is very loud. Right brake is quite.
Light does not work properly.
Wrong seat post was sent with bike so I can't ride the larger cushioned seat i had bought too.

After 3 days of riding, i have 3 redesign suggestions:
1. Move water bottle up so that it doesn't interfere with foot going through step through;
2. Turn the cover for the charger input upside (to cover the opening) down so that water is less likely to enter if open when raining; and
3. The display does not show when the battery is being charged. I can only guess it's being charged because the charger fan is blowing.
I will try to be at the shop next week to fix theses items.

The alarm works great but the biike tips to much on slgt humps on the rpad.in my city there is tree roots pushing up tje sidwallke every ten feetmuc.h to tipee to ride. I didn't intend on returning the bicycle but because I throw it through the box away now I'm stuck with it otherwise I would return it for a refund and buy something else it's safer for me I'm 70 years old so it's just a little too sketchy
