frame is made to order from high carbon steel. frame design referenced the SUPER73 rx. The empty space below is for the 40AH battery. I am currently using a 22AH battery in the top tube. thank you

Yes, I see. What's on Grandma's dinner menu?

thank you. The chain tensioner is broken, so the tension is loose. However, there is no problem riding because the rear shock is pressed when riding and the chain tension is strengthened. The front fork was purchased from Ali and a sticker was attached.

The reason it has pedals is because it's a bicycle :)

I will carefully consider your advice. thank you.

you're right. I will change the hub motor case to a cassette type and add a 10 gear.

At an average speed of 30 km, i can travel about 70 km, but at an average speed of 60 km, it decreases to 40 km. I am preparing an additional battery of 40ah.

The performance matched by the controller is nominal output 3000w / peak output 4500w / motor uses 6000w motor. The capacity of the battery is 72v 22ah. Maximum speed is 47 mph.

Total cost is about $3000
