They responded kindly to inquiries and consultations, so I purchased it even though it was a higher price than other companies. The product took more than 15 days to arrive, so it was disappointing that there was no manual. I guess they didn't deliver the tail lights they said they would send. Other than that, I received the product very well. I'll drive test it tomorrow. I've driven 300k miles in a week. Looking at it, I feel like I made a good purchase. It has good power and runs well. Other bicycle enthusiasts are jealous. The power in double mode is very good. The front and rear wheels run well. There was no manual, so I had a hard time learning it on my own, but I am glad that the seller responded well to consultation. I had no worries. Delivery took a few days longer than expected and there was no manual, so I initially gave it 3 stars, but if I were to give it again, I would give it one more star.

I received the product at the promised time, and after assembling it, I really like it./It is easy to use in combination with electric and manual type/The bicycle wheels are liberated, so the stability is good. I like it very much./ Thank you./ It would be better if the delivery was a little faster. / Thank you, seller.

This is my first electric bike, and I really like it. If you ride in dual mode, it's hard and it's easy to go uphill. Good buy. ^^
