- Early stage (late 19th century – 1980s)：The electric bicycle can be traced back to 1895 when Ogden Bolton installed a DC hub motor on the rear wheel to create the first electric bicycle1. However, from this period until the 1980s, the development of electric bicycles was in a very preliminary stage, and the relevant technologies were still being explored. In terms of braking components, the braking systems of bicycles were basically adopted, mainly simple mechanical brakes such as the caliper – type brake. The caliper – type brake adopts mechanical transmission and realizes braking by the braking device holding the edge of the wheel. It has a simple structure and low cost, but the braking effect is limited, and it is easy to make a sharp whistling sound when braking6.
- Development stage (1980s – 1990s)：In the 1980s, the first Yongjiu – brand electric bicycle was produced in Shanghai in 1983, and Yamaha in Japan successfully developed the prototype of an electric bicycle in 19891. In this stage, electric bicycles began to receive more attention, and the braking components also developed to a certain extent. In addition to the continued wide use of caliper – type brakes, drum brakes began to be applied. The drum brake adopts mechanical transmission and uses the friction between the brake shoes and the brake drum to brake6. Its braking resistance arm is smaller than that of the disc brake, but its braking effect is better than that of the caliper – type brake. It is relatively cheap, and the drum brake pad is wide, with a large friction torque, small wear and long service life6.
The following is a summary table:
| Time | Type of braking component | Characteristics |
|---|---|---|
| Late 19th century – 1980s | Caliper – type brake | Basically adopted the braking system of bicycles. It has a simple structure, low cost, limited braking effect, and is prone to making a whistling sound when braking. |
| 1980s – 1990s | Caliper – type brake, drum brake | The caliper – type brake was still widely used, and the drum brake began to be applied. The braking effect of the drum brake is better than that of the caliper – type brake. It is cheap, the brake pad is wide, the friction torque is large, the wear is small, and the service life is long. |

Technical Background and Evolution Liquid cooling represents the third revolution in electric bicycle battery thermal management, emerging in the mid-2010s and continuing to evolve. As battery energy density exceeded 250 Wh/kg (e.g., CATL CTP3.0) and 800V high-voltage platforms became widespread, peak heat generation reached 15-20 W/cell. Traditional air cooling (efficiency ~500 W/m²) became insufficient, prompting the adoption of liquid cooling. This technology improved heat dissipation efficiency to 1500-3000 W/m², becoming standard in premium models. The development can be divided into three phases: Stage Timeframe Technical Features Representative Models Market Share Pioneering 2015-2018 Cold-plate liquid cooling (e.g., Tesla Model 3 battery cold plates), non-standardized, high […]

Compact Folding E-Bikes Under $1600: Best Value Picks
Tight on space but eager to ditch the car? We get it. That’s why we spent the past six months testing and comparing compact folding e-bikes under $1,600. Whether you’re commuting in a dense city, hauling your bike onto a train, or squeezing it into a closet, these value picks offer the best mix of portability, performance, and price. 1. Why Compact Folding E-Bikes Are Taking Over Our Commutes We used to think folding bikes were clunky, slow, and not really worth the effort. That changed when we started relying on them for our daily rides around town. Living in a city where parking is a myth and sidewalks are always crowded, a folding e-bike gave us a way to move fast—without worrying where to stash the thing afterward. But what surprised us most was how good the affordable models are getting. You don’t need to spend $3,000 for something solid, compact, and reliable. In fact, everything we recommend here costs less than $1,600—some even under $1,000. 2. What to Look for in a Sub-$1600 Folding E-Bike Before diving into our list, here are the essentials we kept in mind while testing: 3. Our Favorite Picks (Real-World Tested) 1.Ecoe 5000W Dual Motor Electric Bike — $1,599 Why We Like It: Okay, this one’s a bit beefier than typical folding bikes, but we had to include it. With dual motors, 60V 32AH battery, and 26×4 fat tires, it’s the most powerful and long-range option we tested under $1,600. Yes, it folds (partially), and for heavier riders or longer commutes, it’s unbeatable at this price. The Ecoe brand may not be mainstream yet, but it’s definitely performance-driven and urban mobility focused. 2. Aventon Sinch.2 — $1,599 3. Ecotric Dolphin — $969 4. Ancheer Folding Commuter — $679 5. Lectric XP Lite — […]

How to Choose the Perfect Folding Electric Bike: Ultimate Guide
In today’s fast-paced cities, finding the right folding electric bike (or “folding e-bike”) can mean the difference between a stressful commute and an enjoyable daily ride. In this ultimate guide, we share everything we’ve learned—through trial, error, and real-world riding—to help you choose the perfect folding e-bike for your urban lifestyle. 1. Why We Chose Folding E-Bikes in the First Place Let’s be honest—parking sucks, traffic is worse, and public transit isn’t always reliable. That’s why, a couple of years ago, we decided to ditch the subway and invest in folding electric bikes. What started as a curiosity quickly became a lifestyle shift. Folding e-bikes gave us the flexibility to zip through traffic, fold the bike under our desks at work, and even take them on weekend trips. We’ve since tested nearly a dozen models, each promising something different. But as we learned, not all folding e-bikes are created equal. 2. The 6 Key Features to Consider Before You Buy Here’s what we now know really matters: A. Weight & Portability If you can’t carry your e-bike up a flight of stairs or lift it into your trunk, it defeats the point. For us, the sweet spot was under 50 pounds. Anything heavier became a chore—even if it folded nicely. B. Fold Size & Mechanism Some bikes say they fold, but end up being bulky after folding. We looked for bikes with intuitive 3-point fold systems, compact enough to fit in an office corner or train luggage rack. C. Battery Range You don’t want your e-bike dying halfway through a commute. We prioritized models with a minimum range of 30 miles—enough for daily use without recharging constantly. D. Motor Power A 250W motor works if your commute is flat and easy. But if you have hills or need speed, 500W […]

Front and rear disc brakes ensure safe, responsive stopping, whether on mountain trails or city streets. – 1. Technical Background and Evolution The forced air cooling stage served as a critical transition between natural cooling and liquid cooling for electric bicycle battery thermal management, spanning from the late 2000s to the early 2010s. As lithium-ion battery energy density increased from 100-150 Wh/kg to 200-250 Wh/kg, heat generation during high-rate charging/discharging surged (up to 5-8 W per cell). Natural cooling became insufficient, prompting the adoption of forced air cooling. This technology improved heat dissipation efficiency by 30%-50% through active components like centrifugal fans and axial fans. 2. Technical Principles and System Architecture 3.

Front and rear disc brakes ensure safe, responsive stopping, whether on mountain trails or city streets. – In the early stage of the development of electric bicycles, due to the limitations of battery technology and the performance of electric bicycles, the heat generated by the battery was relatively small, and the requirement for the cooling system was not high. Therefore, the natural cooling method came into being and was widely used. At that time, electric bicycles mainly aimed to meet the basic travel needs. The battery capacity was small, and the cruising range was also short, generally about 100 km, and the battery pack capacity was about a dozen kWh. Natural cooling relied on the convection of natural wind between […]
