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.
Electric mountain bikes have garnered a lot of attention for their ability to help riders go higher, further, and faster on the trail. As a result, there have been some impressive new eMTB models to hit the market in recent years, making it easier than ever to head off-road. Our favorite is the Haibike SDURO HardNine, which comes equipped with a 350-watt Bosch Performance CX drive and a 500 watt-hour battery. This gives it a range of up to 70 miles, along with a top speed of 20 mph, which is plenty fast on singletrack.

Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.[43]
TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,...
There are various kinds and classifications of electric bikes on the market, but the more common type is the Class 1, or pedal assist, bikes which have motor units that are activated by pedaling and are limited to lower speeds. In the US, Class 1 electric bikes, the type tested and reviewed here, are limited to a top speed of 20 mph and their motors are designed with a speed governor to regulate this. These types of e-bikes resemble modern mountain bikes, but they have significant battery packs and small motor units integrated onto and into the frame design. The e-MTB pedal-assist motor is typically built around the bottom bracket and provides varying levels of pedaling "support" directly into the drivetrain while the cranks are turning. Most drive unit systems offer several support settings that provide pedal assistance between 25% and 100% of the user's pedaling input.
As my boys were growing up in the 2000s, we would bike together in local parks and I always dreamed of taking them on my favorite big rides when they reached their teenage years. But in 2012 I started getting sick and I didn’t know why. Two years later, after countless doctors visits, tests, and head scratching, I received some bad news from my doctor: somewhere in my adventures, I had contracted Lyme Disease. My life has never been the same.
The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.
The Benno e-Joy promises to be as fun to play with as it is to look at. Benno says it took inspiration from the timeless style of vintage Italian scooters and classic German cars. Add in the functionality of front and rear cargo racks and the 250w pedal-assist motor and you have a beautiful bike that's ready for anything. Cruise into town for groceries, wander comfortably along a gravel path on 2.35-inch balloon tires, or add the child seat attachment and take your kid along for the ride, and beach-goers will appreciate the surfboard rack. Whatever your cycling pleasure pursuit may be, the e-Joy can be your ticket to fun.

The electric bike revolution has officially crossed into the arena of off-road motorbikes. For those who prefer riding in nature, Cake introduced a product which not only respects the environment but other riders, as well. Cake’s Kalk is a silent off-road motorbike that releases no emissions into the atmosphere. Additionally, its electric motor means no gear changing or clutching — a silent motorbike that won’t detract from the experience of others. Perhaps the best part is Cake avoided any sacrifice in performance. The Kalk reaches speeds of fifty miles per hour and features three distinct driving modes: Discover, Explore, and Excite.
If you’re looking for even more performance and an even more refined bike, you’ll find what you’re looking for at Specialized. Their bike embodies the company slogan “Innovate or die” in a perfect way and is full of smart solutions. Many of them, such as the specially developed app for tuning the motor, the integration of the battery, and the small remote lever for selecting the support level, are obvious. Some, on the other hand, only become clear when you take a closer look – such as the Autosag valve on the shock for a simplified setup process, or the omission of a spoke magnet. The Levo also won us over with its outstanding riding characteristics, obviously. It rides comfortably, climbs quickly and efficiently, and has exactly the right mix of agility and stability. It’s the ultimate machine that promises to bring a huge smile to every rider’s face after just a few metres on board – no matter whether beginner or a pro. The Specialized Turbo Levo S-Works Carbon is currently the eMTB offering the best overall package, and thus the deserved Best in Test! The best eMTB of the 2018 season!
But astute readers are surely wondering about the specs, as are we. Unfortunately, there is little to no information on it … making it a bit difficult to come up with a fitting name. But, seriously, the only thing we know so far is that it will have a USB charging port and LED lights, according to GM. The automaker bikemaker is keeping everything else secret. Perhaps as it simply hasn’t decided on the final specs. We’re waiting for company comments.
E-enduro bikes aren’t as different to regular bikes as one might imagine. All of the fundamentals are the same and by nailing the geometry and sizing Vitus has produced an amazing e-bike with the E-Sommet VR.Sure there are a couple of little things we’d probably change, like the STEPS Di2 mode shifter and rear tyre, but that’s about it. And given how much cheaper the Vitus is compared to the competition, you can easily afford to make these changes and even buy a spare battery. The E-Sommet VR is no golf buggy, but Vitus has it’s certainly hit a hole in one with this bike.
Definitely not a downhill option, but still great for mountain camping, fire roads, loose and packed dirt, and trail commuting, the R&M Delite Mountain definitely makes the list. This is a mountain bike version of the very popular full-suspension commuters offered by Riese & Muller. The main reason that this bike makes the list is thanks to it’s 1000 watt hour battery potential with a dual battery system.

eMTBs appeal to an extremely broad target group: some use their eMTB for daily commuting, others for after-work or weekend rides on maintained gravel roads, and others plan to do an electrified alpine traverse or even an action-packed visit to the bike park. The good news is that many eMTBs are jacks of all trades, covering a very wide range of uses. Others, unfortunately, may disappoint with poor spec or nervous handling.
