Hi Folks :lol:
I am new here and found this website to be awesome. I have learned a lot of things, and I am planning to log in to this website every day. There are a lot of very good and very professional people.So I want to share with you the following electric bikes I am working on.
I come from China,Like everyone, I love DIY, like motorcycles, electric cars, go-karts, tricycles. In the past 8 years, I have produced more than 10 cars with my friends. More than 50 cars have been modified. They are all kinds of different. This time I want to introduce you to an electric bicycle program.
【1】
I have been making this electric bike with my friends for 5 months. It has the following characteristics.Also what we hope to do.
a. A good looking appearance. We saw a lot of good product designs on Google. (Example: Neematic/KTM/Stealth P7&otherStyle/Audi Ebike/Sun-Ron Lightbee/Harley Davidson Ebike etc.)
b. Lower cost. (The cost of the whole vehicle Below $1000) but the quality can not be too bad...
c. Look forward to the performance of the center motor.

1. We completed the first version of the prototype in March this year. (Iron frame: weight 51kg) The second version of the prototype was completed in April this year. (Aluminum frame: weight 43.7kg) The third version of the prototype was completed in May this year (weight: 36.5kg).
2. Re-creating pipe bending equipment and punching equipment in May and June
3. A total of 3,500km of tests were completed in May. (Continuous improvement, mainly want to reduce weight and cost)
4. A total of 14,000km of tests were completed by June (a total of three prototypes were tested). Contains desert, mud, gravel roads, rainy days. Not very deep puddles, various slopes, drop tests and other routine tests.
5. Give it a name and take some videos. Make a website with Wix. :lol:

6. In the end, we replaced most of the iron with aluminum (6061T6/7075) and the weight was reduced to 29.2kg. (A bit like losing weight, I am worried that the weight may rebound and increase. lol)
7. Consider the frame of the titanium alloy, but the price quoted by the material merchant is too expensive. We only bought a small amount of titanium alloy for testing, because if the price is too high, it is contrary to our original intention.
8. Also tested the performance of high-powered automotive motors, 20kw-35kw. But because of the size, weight, price and other factors, we still do not have a perfect design. At present, efforts are being made to solve this problem.
【4】Our purpose
A. If you need it, we will be in the later open source drawings and BOM and the corresponding production methods and tools list. Considering that he is an MTB, we need to reduce the risk of riding, so I hope to go through more long-term tests, such as: 100000km. :thumb:
B. [DIY KIT] provides the completed frame and related accessories to those who like DIY but have no time.
C. [Customized Service] Some simple modifications and customizations can be made.
【5】 Contact information
Sorry, my English is very poor, so our website uses Chinese. The data on the website will be constantly adjusted. But I can use the translation software to fix it. I can also do a simple spoken conversation. Therefore, I am looking forward to sharing with you.
Our studio is in China, I live in Beijing, but the studio is in Tianjin, Beijing's rent is too expensive.
