best lights for urban commuting

I have a set of 4 (2 back, 2 front) on a folding electric bike that I commute with on pot-hole-filled roads. The middle part of the commute is a train ride where I need to fold it. The lights and back turn signal are really wonderful. The setup was seamless. Monitoring which light needs charging using the phone just takes a second. The mount does not get in the way of folding up the bike, and it does not have much extra width, so that I can easily navigate the train.

Edit : updating my previous review !!! It fits perfectly !!!

I want to apologize for my first review. I first thaught it wouldn’t fit my saddle.

But I finally disassembled completly my saddle and it fits now perfectly on my 2x1000w Lankeleisi MG 740 Plus Speedelec Mountain Bike.

Please feel free to erase my first review.

Good job guys !

Absolutely happy:)

After the unfortunate event that I couldn’t pick up the parcel for the first time, you kindly resent it.
So I received it, and it has a great quality.
Thanks again

Mount vs rear seat bag

The mount fits perfectly. 1 little issue, it is not wide enough when my bag is on my bike.
