Very good product and customer service. Delivery was promised to arrive in April but I received it 1 month earlier!!! ?????? The customer service answered patiently with all my enquires. I requested a 20" for my BMX but the flower pattern will just clash with the bike. The customer service made a request for a black flower pattern and it really look good for the BMX. They also included a very good 20"x2.4 tyres to match my BMX. The product works as it promised. I believe if they let users tweak the software end-users can hack the wheel to add more features like self locking and unlocking if user is near with bluetooth connection like a car keyless lock, programmable battery management and even more.

For Valentine's Day, I bought my wife a conversion kit for her bike. The installation was easy, and she loves how it helps with her arthritic knees. It's so discreet that people don't even realize her bike has an electric motor until she speeds away without pedaling.

With the hills in Pennsylvania, taking a leisurely bike ride used to be exhausting and unenjoyable. But now that I have my Lvbu KX, it's not tough anymore. I love it so much that I'm thinking about buying another one in the spring for when I'm at home.

I am thoroughly enjoying my ebike conversion kit so far. I've been able to double the mileage I was previously doing, and I'm finding that cycling is much more enjoyable with the added assistance. The battery life is impressive as well. During a recent 35-mile ride, I still had 55% of battery life left, which is a testament to the high-quality components used in the kit.
