Folding E-bike Buying Guide – 3 Things to Think About
A crucial consideration is the power that determines the bike’s ability to climb steep hills and ride over rough terrains. An E-bike has several power ratings, but the most significant one is wattage. As a rule, the higher the wattage, the more power the electric bike can muster.
Every electric bicycle has a battery with a voltage rating and a controller with an amp rating, which determines the wattage of the bike. For example, if you have a 36-volt battery and a 15-amp controller, the bike will have a wattage of 540 watts (volts x amps =watts).
Three things determine the wattage you need: your weight, the inclines in your area, and the speed you want to achieve. If you weigh more than 220 lbs. (100 kg) and live in a hilly area, don’t settle for a cheap folding electric bike with a power rating of fewer than 1,000 watts. If you weigh 160 lbs. (72.5 kg) and live in a flat area, a power rating of 500w motor will be enough.
Torque is another rating to consider as it is the hub motor’s ability to turn the rear wheel. This rating determines an electric bike’s ability to accelerate. Your load should also play a role when selecting an appropriate power rating. Take the weight of your kids, their child safety seats, and your bags into account when considering a suitable power rating.
The type of bike you choose should be suitable for your needs. Each type of electric bike has a unique construction, design, and power rating to cater to specific customization.
Electric Folding Mountain Bikes
These electric bicycles are popular among people who like to explore the outdoors with the assistance of motor power for steep hills and rugged terrain. The bikes are larger than road bikes, and typically have limited packing space and load capacities.
Electric Road Bikes
Electric road bikes are like conventional road bikes in design and load carrying capabilities. Typically, people who like riding bicycles to stay fit don’t prefer this alternative, but it is ideal for recreational activities.
Electric Hybrid Bikes
Electric hybrid or power assists bikes are becoming increasingly popular to commute to work and other places, like retail stores. These functional bikes are not as impressive as electric mountain bikes, but they have high load capacities for groceries, luggage, and briefcases. Of all the cheap electric bikes, hybrids are the most popular.
The wheel size of your electric folding bicycle is significant as it determines the terrain you will be able to handle. Wheels with a diameter of 20 inches or more provide a smooth, stable ride over rocky, sandy, and slippery surfaces, as they have better roll-over characteristics. Larger wheels have more rubber on the ground, providing better traction and making steep climbs much less challenging.
Some people prefer smaller wheels as they are lighter than fat tires. This bike doesn’t require the same clearance, which makes a smaller frame possible. Smaller wheels may also be the better option for people who prefer the enhanced maneuverability and control of a small folding electric bike.
The size of the wheels might also affect how small a bike can fold down. If you want it to fit comfortably into public transport, a 20-inch wheel will be enough. If your storage space if more compact, consider a 16-inch wheel or smaller.
How Does an Electric Folding Bike Work?
An electric folding bike has the same construction as a conventional bicycle without electric power. The primary difference is that an electric bike has additional components to turn the rear wheel effectively. Other features of an electric bike include a battery, electric motor, sensor, and electronic display, typically not found on normal bicycles.
The battery pack provides the E-bike’s driving power. Most electric bike kits use a lightweight lithium-ion battery that offers ranges of 10 to 40 miles on a charge. You can extend this range by pedaling over a portion of the journey.
The battery powers an electric motor that can be fitted to the rear or front wheel. Some motors power the bike’s pedal sprockets. Full-power bikes have larger batteries and powerful motors and are designed for as little pedaling as possible. Power assist or hybrid bikes have electric systems to drive the bike when you are tired or need a boost when climbing steadily up a hill.
How Fast is the Fastest Folding Electric Bike?
Your pedaling ability limits a foldable electric bike’s speed considerably. The electronic drive system of most E-bikes will stop assisting with a speed of 20 miles per hour. These bikes fall under Class 1 and 2 categories and are also called low-speed throttle-assisted bicycles.
High-performing models power the foldable bike at speeds of up to 28 miles per hour. These are considered Class 3 bikes and are called speed pedal-assisted electric bicycles. The fastest bikes on our list can reach speeds of 20 miles per hour.
How Much Does the Lightest Electric Folding Bike Weigh?
The best folding electric bikes are heavier than regular ones you can buy on Amazon because they have enforced frames. They also carry additional equipment like a battery and motor. Weight affects the performance of an electric bike, and a lightweight model is easier to lift and load into a storage space or car trunk.
High-end bikes can weigh as little as 17 lbs. (7.7 kg,) but these models are not as powerful as the E-bikes between 30 and 70 lbs. (13.6 – 32 kg.) The lightest bike in our list is the Kemanner 26″ Electric Bike that weighs 40 lbs. (18 kg.) The bike’s low weight makes it incredibly easy to ride, and you will get 15.5 miles on a single charge.
If weight is a concern for you, this model may be the most viable of all the E-bikes on the market. Weight is not everything, however. If you are planning on transporting heavy items, a more robust frame will provide the support you need.
