And then add in all of the other e-bike parts including motors, batteries, throttles, speed controllers, etc. All of these parts are mass-produced in China. They simply aren’t available in the US and no one is designing them or manufacturing them. The US would likely have to start by reverse engineering the Chinese products and learning how they produce them. How’s that for irony?
A representative for Ancheer, a California-based e-bike company that sells some of the most affordable e-bikes in the US, expressed dismay over the tariffs in an interview with Electrek. Ancheer will regrettably be raising prices on their electric bicycles, but intends to try to absorb some of the cost to avoid passing on the entire 25% tariff to their customers.
Whether the terrain is flat or hilly impacts the distance you can travel, as does the weight of the bike, your own weight, the gearing available on the bike, and how much juice you give it. We suggest that a distance of 10 to 20 miles is a realistic expectation. Of course, if you're prepared to do at least some pedaling, you can extend that dramatically.
We rode the Vado through the gauntlet, including some of the steepest hills in Palo Alto, and it easily handled everything we threw at it, maintaining a steady 20 miles per hour even on the most daunting of ascents. The bike also handles well on downhills and is both nimble and quick on city streets and paved trails. It’s even comfortable to ride for extended distances, which is vitally important for any bike built for urban settings.
This bike impressed me right when I saw it. I love that Haibike offers spec-heavy options with the Yamaha PW system. I think the PW system gets a bad rep sometimes for being less powerful than the Bosch, but to be totally honest not everybody needs the power of a Bosch system. Haibike makes up for the lower torque of the PW system by offering a premium Shimano Deore XT drivetrain with 20 speeds. This is great for riders who want to stay in the action a bit more, but still not arrive sweaty and out of breath.
Electric Bike Technologies has been delivering the best experience in electric bike kit conversion since the company was founded in 2008. Driven by a respected founder and a team of dedicated electric bike enthusiasts, the E-BikeKit™ electric bike conversion systems have been sold worldwide to thousands of electric bike riders and fostered partnerships with some of the best brands in the bicycle industry. The company has been featured on NBC’s Good Morning America and the E-BikeKit system is the only electric bike kit system distributed by J&B Importers, the largest bicycle distributor in the United States.
In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles,[1] while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small motorcycles.[2][3]

Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike.[9] The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.

It’s impressive just how traditional a finish they’ve achieved for a pedal-assist bike, especially considering the motor uses Kinetic Energy Recovery to charge itself (like F1 Cars). Firing up the motor is achieved by back-pedaling three times (while travelling over 8mph). It’s a neat idea, and a clever way of doing away with those cables and switches, but in reality it’s fiddly. Riding in the city we occasionally felt ridiculous on a busy street pedaling backward rather than forward to kick off the assist. It’s also a chore getting the bike to speed and going through the motion to activate in tight spaces such as underground garages or on an incline.
This bike is designed for hauling. The Yuba Spicy Curry has a combined capacity of 500lbs (200lbs on the front including rider, and 300lbs of passengers or cargo on the back). To help move this weight, you’d expect a decent motor, and the Bosch Performance Line CX delivers. Normally only found on mountain bikes, the 75Nm of torque makes light work of hills, even with the heavy load.
The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.
Haibike ships the HardNine with 29-inch tires, 180-millimeter hydraulic disc brakes, a 100-millimeter front suspension fork, and a nine-speed Shimano shifting system. The bike’s LCD readout is affixed to the handlebars and displays the current speed, level of charge, remaining range, and current pedal assist mode. The company says the battery can be completely recharged in just four hours, minimizing downtime between rides.
Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.
“I can go on Alibaba, buy parts, set up shipments, and get people to buy these things,” she says. “The question comes on the support side. Will they have spare parts? Will they have tech support? Do they carry insurance? Real manufacturers of e-bikes have serious insurance in case something goes haywire or someone has an accident. That’s $20,000 to $30,000 a year.”

On the other end of the pricing spectrum (although not as high-end as possible) falls the Riese & Muller lines. The Nevo line, which features a Bosch motor, hydraulic disc brakes and speeds up to 28 mph also has a roughly $5,000 sticker (a variety of models allows for a cheaper price). Using a carbon belt and Nuvinci grip shifter, maintenance worries lessen. The German-made premium models are hand made to specifications and comfort reigns supreme.
Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.
The Ancheer comes with outstanding Shimano Tourney gears in 6 x speeds. This gear system is one of the best in the business. Similarly the front-rear disc brakes are perfectly effective and will bring you to a safe stop even from speed. Speaking of speed, the maximum is 16mph and the bike will travel anywhere between 17-23 miles on a single charge. The battery charges up in 4-6 hours, which is the same for virtually all e-bikes.
Most consumers want an e-bike that will accommodate its motor without being too cumbersome and will remain stable in spite of its electronic components. Some consumers want only the most basic of e-bike features, including lights, a cargo rack/basket, and a water bottle holder. Others are focused more heavily on safety features, such as brake type. And still others are concerned with convenience and portability.

At the end of the day, you'll have a ton of fun riding one. “There’s that nostalgic feeling that kicks in whenever you’re on one, that feeling you got when you started riding as a kid," LaLonde says. You might have to get on one to understand, but there are few things more smile-inducing than floating up a steep hill with little effort, Mary Poppins-style.
Riese & Muller’s Nevo line definitely tops my list for commuting electric bikes. These bikes are premium, custom made bikes for a reasonable, middle-of-the-road price. All Riese & Muller bikes are hand made in Germany exactly to your specifications. The Nevo line specifically is incredibly well balanced and keeps riders in a comfortable, upright position. Riders also get a suspension seatpost (either the Cane Creek Thudbuster or Satori Elegance LT), which is a nice compromise between the full suspension Homage line and a complete hardtail.

The body is made from light and durable aluminum. The handlebar comes with simple controls to let you accelerate, brake, monitor battery life, operate headlights and of course…sound the horn. There’s even an USB point that will let you charge your iPhone or Android on the go. The bike can reach a top speed of 10mph. Feel the wind in your hair as you zoom up and down hills and past all that city traffic…
In addition, Kalk weighs under 155 pounds — less than half of traditional motorbikes. Cake customized parts of the drivetrain and implemented an interior permanent magnet (IPM) motor. On a single charge, the bike travels up to 50 miles and as a bonus feature, maintenance is minimal due to the fact there are few moving parts thanks to its lack of a combustion engine.
On a trip to Palo Alto last year, we had the chance to ride Specialized’s pedal-assisted Turbo Vado and the model is still our favorite ebike on the market. Utilizing a 350-watt motor and 604-watt-hour lithium-ion battery, the Turbo Vado is capable of traveling a whopping 80 miles on a single charge, which should be more than enough for any daily commute with plenty of miles left over.
It really is a simple e-bike, and while I could go on about the frame (aluminium), and the weight (very light), the experience of using this bike for a few days is more interesting. While it feels like a less high-tech product than others in this list (no gears; a shorter battery life of 30 miles; two modes not three), it basically retails at half the price as those competitors – and I certainly didn't find it to be half as good.
To help the rider find the perfect fit, the stem is adjustable. The bike also boasts dynamo powered lights alongside hydraulic disc brakes. The bike will suit riders from 4 ft 10 to 6 ft 5, and also integrates with a child seat. The total weight is 21.8kg, making it admittedly a fairly hefty folder – but that’s fairly uniform across electric versions.
Kalkhoff's electric-assist bicycles start with the same high-quality, sleekly designed bikes that Kalkhoff has been developing for 90 years. A state-of-the-art, brushless, centrally-located motor provides a smooth, predictable power-assist directly to the drive train. Kalkhoff e-bikes come fully-equipped with a variety of features to ensure that your commute, shopping trip, or outing is safe, comfortable and fun.
Because e-bikes are capable of greater speeds for longer periods of time than standard bikes, you want extra control. Wider tires provide traction and some bump absorption with little penalty. You also want strong brakes to slow you (and all that extra weight) easily. It's worth looking at the quality of the brakes and investing in bikes with better ones if you can.
