We found the Groove motor a little laggy in engagement, with often almost a full rotation of the cranks before the assist engaged - compared with the Gazelle and Vanmoof, the pick-up was frustrating. Putting our issues with the assist to one side, we couldn’t fault the aesthetic: we loves the semi-mixte frame style, a practical non-gender specific design.

You know the saying, “What you see is what you get?” That’s pretty much the case here: An e-bike or "pedal-assist" bike is a pedal bike with an integrated electric motor that adds power when you pedal. It's not like a motorcycle, moped, or motorbike, because it doesn't have a throttle or engine. Think of it like when you get the rocket boost in Mario Kart (except it lasts for more than three seconds).
The Nuvinci hub system is the best geared hub that I have ever used. There is literally no maintenance to be done on this drivetrain. I’d recommend buying it with the Gates Carbon belt because you’ll never run into issues like the chain falling off. You operate the Nuvinci system with a grip shifter and can of course shift even when you’re not moving.
I think this is a super interesting bike. I like seeing IZIP stepping into the world of Brose motors. Brose bikes always look clean and refined because of the battery integration. This bike is a pretty great value for what you get. Totally integrated lights, rear rack, fenders, and plus sized tires are all great to have. I wish it had a dual chainring in the front, but you can always add one on a Brose motor.
FRAME GEOMETRY  EcoBike electric bikes have been specially designed with the daily commuter in mind. The frame is constructed from a high-strength, lightweight 6061 aluminum alloy that maximizes safety and durability.  The enhanced frame design features comfort ergo-geometry that is more upright than a traditional mountain or road bike.  Every EcoBike electric bike is outfitted with suspension on both front forks (except Vatavio) and seat post to deliver a smoother ride. 
To be honest, this bike is really designed for city commuters or kids riding around the suburbs. The fact that it’s foldable will let you carry it on the bus, on the train or even on the plane. It’s just not designed for heavy riding, long distances or tough terrains. If you want something sleek and fabulous at a fraction of the cost of most other e-bikes, this baby’s for you.
As a counterbalance to the cute utilitarian bikes above, the Specialized Turbo Levo FSR Comp is a big, bad, and burly mountain bike. With 27.5-inch wheels, massive 2.8-inch tires, 150mm of travel in the front and 135mm of travel in the rear this bike is made to shred. The Specialized 1.3 Rx Trail-Tuned motor is designed specifically for off-road riding and features a double freehweel design that disengages the gear box at top speed to reduce friction while ripping downhill. The low center of gravity and stout parts make this one a relatively nimble handler that is ready for the rowdiest downhills.

China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[72][73]
It will be of little surprise to learn that the Hanebrink all-terrain vehicle was designed by six time Mountain Bike national class champion and former U.S. National Team member Dan Hanebrink. It's based on 1993's Extreme Terrain fat tire pedal bike and is made to order at the Fortune Hanebrink workshop at Big Bear Lake, California. Echoing the philosophy of many electric assist bicycle makers, Hanebrink says: "We are not trying to replace standard bicycles, we want to replace cars and trucks."

As with all these bikes, the assisted speed is capped at 15mph, but unlike some of them, the Gtech eBike City or its identical (spec-wise) sibling the eBike Sport (this just has a standard frame rather than a step-through one) is light and agile enough for you to be able pedal harder without feeling like the weight is fighting you back down to 15mph. You can even, at a push, use it without the motor on flatter roads.

Because they’re electrically powered, e-bikes sit in a bit of a gray area between bicycles and motorcycles. While some states have enacted specific legislation to state where electric bikes can and can’t be ridden, in other states outdated laws mean they’re regulated as a moped or motor vehicle which can cause confusion over registration requirements, access to cycling infrastructure and how old you have to be before you can ride one.

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]


Over the last few years, I’ve taken my love of the outdoors, hiking, skiing, trekking and exploring to the next level by starting this site. I started a bike shop in Denver, CO, and have seen amazing growth over the last few years. Getting paid to do what I love has been a dream come true for me. That’s also what led me to start BikesReviewed.com. In my shop, I spend a large amount of time helping people find the perfect bike for them and the style of biking they’re going to be doing. It only made sense that I expanded my reach and got online, making it possible for me to help people all over the world. If biking and staying fit is your priority, too, you’ve come to the right place.
Everyone seems to know a lot about Haibike’s e-MTBs, but I think their commuting and touring bikes are just as good, if a little bit underrated by the e-bike community. Another bike with the Bosch speed motor, this bike is quick and powerful. I really like the spec upgrades on this bike from the Trekking speed model in 2017. You’ve got Magura MT4 hydraulic disc brakes, a Shimano Deore XT M8000 Shadow Plus drivetrain, and the headlight and taillight run off a dynamo.

In 2012, two e-bike advocates completed the first 4,000-mile (6,400 km) transcontinental e-bike tour from New York to San Francisco to advocate for e-bikes in major cities across the U.S.[81] Pedego Electric Bikes is the best selling brand in the U.S. Many e-bikes in the United States are standard bicycles converted using a kit. In general, the kits include the motor (the majority of which are hub motors built into the front or rear wheel), a speed controller, throttle (usually twist-grip or thumb throttle), necessary wiring and connectors, and a battery. Several U.S. companies offer conversion kits which also offer advanced lithium battery packs. Major manufacturers also offer complete e-bikes. Trek offers a line of e-bikes using the Bionx system in which the rider programs the controller to determine how much effort the motor will give in response to rider effort, from 25% up to 200% of the rider's power. This system ensures a minimum level of rider participation and is also used to comply with many European laws mandating partial human effort before the motor engages.
The new Electric Bike Kit Owners group on Facebook has taken off within the first week of its creation. Around 400 people have joined the online group with new members being added every day. E-bike riders are sharing the various ways that they have converted their bikes using the E-BikeKit Complete Electric Bike Conversion System. Each one of the electric bike conversions is more unique than the next. Some e-bike...
In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.
What a treat to do business with the folks at Hill Topper. I now have two commuter units one in Idaho and one in Denver my average ride is 25 to 35 miles. I have been riding for about 15 years but being the age of 80 I needed a little help the past few years. I researched electric bikes a few years ago even rode a couple here in Denver but I wanted my own personal look and feel. So about five years ago I found Hill Toppers. What a treat first the units are the best but that is part of the good part the people at Hill Toppers are the very best to work with and enjoy. I had to have a knee replacement last July well thank god for my bike it was the best therapy I could ask for. When in Idaho I get to ride along the Snake river what a treat knowing that I have this unit to help if the wind or rain shows up. When in Denver I cover a lot of area as they have wonderful bike trails all over the area. I ride all of the downtown area and the Cherry Creek dam up and over it takes some effort to get that done but with the help of Hill topper it is a beautiful ride up and overlooking the whole of Colorado. Thank you Andrew,Charles,Sam,Mark.

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.
Simplicity powers the Gtech model, available in either a 20-inch “sports” crossbar frame or a 17-inch “city” step-through option. From using a carbon belt drive to a gearless system that allows a computer to adjust speed while pedaling, not only has Gtech streamlined the e-bike process, but they’ve also dropped the price to just north of $1,000. At a range of about 30 miles, this 35-pound bike offers a humble introduction to e-bikes.
Gearing: none (many hub motors, one motor revolution = one wheel revolution), fixed gear reduction for more torque, varies when geared motor drives the chain through the bicycle gears which increases torque about 50% (in low gear) for better hill-climbing and offers better top-end speed (in high gear) than direct drive systems using motors of similar wattage.

Cargo bikes and city bikes are common in the e-bike space, but until recently we haven’t seen that many performance road bikes. The Giant Road E+1 is a pedal-assist performance road bike that’s made for more than just commuting; the powerful motor can rank you up to 28mph very quickly on the highest setting so you can rip the flats, join your local group ride, or blast through the mountains with far less effort than a traditional road bike. Don't expect it to feel like a 16lb race bike when you lean it into high-speed turns, but the endurance-oriented geometry allows for an aggressive position on the bike and keeps the it nimble and agile at high speed.
