A professional electric bike company Vanpowers Bike has launched the City Vanture, the world's first e-bike with an assembled frame for city commuters. Vanpowers Bike has launched a crowdfunding campaign for City Vanture on Indiegogo, on May 24, 2022. 

The frame of this great electric bicycle uses the ancient Chinese tenon-and-mortise structure, achieving superior riding experience and safety. Frame comes in more than ten customized colours.

The tenon-and-mortise structure used by the frame is used in architecture 7000 years ago. In ancient times, this structure could make a building stand for thousands of years without a nail.

The Assembled Frame Achieves Perfect Balance and Safety

Many one-piece frames on the e-bike market are mainly heated at high temperatures after welding, followed by repeated manual shape correction and polishing. However, after more than two times of such processes, the frame becomes very fragile and causes frame deformation, comes with high scrap rates. The welding and polishing process results in an uneven and fragile frame structure that can be strenuous and unbalanced when riding.

To solve the problem of the instability and fragility of the one-piece frame, after years of continuous exploration, Vanpowers Bike finally created the world's first electric bike with an assembled frame - City Vanture. 

This assembled frame combines ancient Chinese tenon-and-mortise structure with modern industrial technology, which can withstand large loads, reducing the symmetry deviation of the frame and ensuring the frame's strength to significantly increase its stability. Workers have used the tenon-and-mortise structure for over a thousand years. This structure furnishes a strong outcome and connects by either locking it into place. City Vanture is the world's first electric bike to use this technology.

To ensure the quality, Vanpowers Bike sacrificed a part of its profits to build professional electric bicycles. A brand with good faith will suffer high scrap costs, so its price will correspondingly increase. A poor brand, however, will produce directly, bring the hidden danger of frame breakage for future riding.

The tenon-and-mortise structure of City Vanture controls and reduces centerline tolerances and helps the joint force move forward. The assembled frame is more stable, so the riding experience is smoother, and the safety of the electric bicycle is significantly improved. It can also minimize the rejection rate in the production process, which is environmentally friendly. The battery can be safely disassembled and reassembled when normal maintenance is required, realizing the recyclable utilization of the electric bicycle.

City Vanture frame has special screws and lock nuts. The screws are made of carbon steel with a strength of 12.9 and are 2mm longer than those on the market. Other parts are made of 8.8 stainless steel bolts. The screws at each position have corresponding torque value requirements to enhance the stability of the frame. City Vanture's manual will specify how much torque is required for each screw.

The frame of a bike is like the heart. It has to be strong to withstand all the shock and force of the rider. Vanpowers Bike puts safety first, creating the world's first electric bike with an assembled frame in response to the stability and safety problems common in the e-bike market. ''We named it the City Vanture. We hope it will create a unique adventure for city commuters.'' Vanpowers Bike said.

Smooth and Superior Riding Experience 

A great e-bike is engaged and active with the rider, rather than just passively transferring energy. City Vanture uses a brushless high-speed hub motor. The 350w motor, sensor and controller are three-in-one integrated, which is more convenient for disassembly and assembly. City Vanture is lightweight and ranges up to 50 miles (80km). The US version motor is 36V/350W, which can make your riding speed up to 25mph (40km/h). 

City Vanture is a pedelec that meets the EPAC requirements, complies with the law of EU, and is EN 15194 certified. The EU/UK version motor is 36V/250W with assist speed up to 15mph (25km/h). City Vanture's excellent 1-5 levels acceleration gives you the feeling of loading a bow and release, the balance of the frame gives you a smoother ride, and the twisting forces allow you to drive through corners effectively.

 At high speeds, stable riding and flexible braking are crucial. The City Vanture uses a GatesŸ belt instead of a typical chain. The GatesŸ belt has outstanding durability, is perfectly silent, lighter than chains, drives shifts well, and last 3-4 times longer than chains. A GatesŸ belt can last nearly 20,000 miles. You don't need to get your hands oiled, you don't need a chain. If the belt gets dirty, just wipe it with a rag dampened with water. Never bother with your old dusty chain again. The belt is impervious to water and salt, and there is no problem with rust when riding in wet seasons. It can also bring a smooth riding experience in harsh riding conditions.

The City Vanture's TektroŸ hydraulic disc brake features superb braking power, simple adjustment, and easy maintenance. It has unrivalled durability, stability, and ergonomics, smoother than a mechanical disc brake. A super stable and silent drivetrain and powerful and responsive brakes make riders safer on the road. A great bike is a reliable machine. In city bikes, high-quality brakes, excellent drivetrains, and durable tires are the driving force behind Vanpowers Bike's constant quest.

The central IP66 waterproof colour LCD with high resolution and brightness can show the 1-5 PAS levels, odometer, trip, current speed, battery, and walk assistance, which can assist when the rider pushes the e-bike. Multiple PAS levels can bring more extended endurance mileage and save power.  The display control panel located on the side of the handlebar is convenient for one-handed operation while riding. At the same time, the large screen and great interaction design can make it easier for cyclists to concentrate on cycling and reduce safety risks.

Unique Smart Dual-battery Module 

With the stable 36V 7Ah LG3500 lithium-ion battery, City Vanture can be fully charged in just two hours and provide 50 miles (80km) of mileage. The cool thing is, that you can install an extended battery to extend the range up to 80 miles (130km), at top speed, equivalent to the distance from Long Beach to Legoland, CA, enough for you to explore the city. City Vanture's unique smart dual-battery module on the extended battery can automatically identify the consumption and capacity of the original battery and the extended battery simultaneously. 

When it is recognized that the original battery remaining is too low, the extended battery will be automatically connected, and the two batteries will be used together. So that it can effectively slow down the power loss and be energy-saving, and the battery service life will be longer. The dual-battery module achieves a brilliant balance, significantly improves the use of efficiency, and extends the longer endurance mileage. 

With a total weight of only 34lbs (15.5kg), City Vanture made by a lightweight 6061 aluminium frame can easily be lifted upstairs and wherever you want to go. The lighter frame allows riders to travel longer distances with less effort.

The battery and frame are integrated by a tenon-and-mortise structure. The semi-hidden cable design is clean and aesthetically pleasing while increasing the sturdiness. Each City Vanture e-bike has an exclusive frame number and undergoes a comprehensive and rigorous quality inspection. 

Frame Comes in More Than Ten Customized Colors 

City Vanture offers more than ten customized frame colours. Carbon Black, Shining Black, Ruby, Neon Yellow, Chalk Blue, Infinite Silver, Camo, Cream, Wood, Neon Green, Neon Purple.

Vanpowers Bike launched the crowdfunding campaign for City Vanture on May 24th. The retail price is US$2399. In this crowdfunding campaign, US$1,399 will get you one.
