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]

The National Institute for Transportation and Communities believes ebikes remove barriers to cycling, such as physical limitations and challenging topography. The results of a recent survey “indicate that, by reducing the physical demands on the rider, e-bikes are encouraging more people to replace car trips with bike trips,” it says. The survey found that 37 percent of frequent cyclists and 27 percent of non- or seldom-cyclists who bought an ebike now primarily use their ebike to commute to work, an encouraging sign for transportation officials who want to increase bicycle commuting.

Cost: Good e-bikes are not cheap, and unlike most bikes, the costs associated with owning an e-bike don’t end when you hand over your credit card in exchange for a shiny new steed. The average cost of operating an electric bike is around $390 a year, including maintenance and charging. You’re also likely to need to change the batteries every 3-5 years so factor that into your costs.
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.
This Saturday, Oct. 7, Tim Sway will showcase his “UpTriCycle” at the Greater Hartford Mini Maker Faire. Sway calls the UpTricycle an “off grid, electric, solar charging mobile maker space and carrier for upcycling makers.” He uses minimal tools and footprints in his creation for unlimited potential. On his YouTube page, Sway made a comparison video between a gas-powered trike and an electric trike. He purchased a gas-powered trike first,...

Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.
The Moterra is Cannondale’s biggest and baddest e-mtb and just looking at this thing you can see that it’s built to withstand some wicked downhills and big drops. With 130mm of front and rear travel, paired up with 27.5-inch wheels and trail-grabbing 2.8-inch tires, along with a KS LEV Integra Dropper Post make this pedal-assist mountain bike a great option if you want to climb farther to shred longer, but don’t want to lug your bike uphill for ages. The 250w motor, placed slightly farther forward than most other bikes to optimize weight distribution and handling, will give you a nice boost so you can enjoy the ride up and not be too gassed when you get to the top. After all, it’s all about the ride down, right?

ELECTRONIC CONTROL  The Zero-Smart-Start speed controller delivers ease of use and smooth drive control and offers a multi-function variable speed output.  It is state of the art, producing consistent efficient power.  The automatic Pedal Assist mode produces a power burst that dramatically assists the pedaling effort.  The Zero-Smart-Start electronic throttle control allows the rider to relax and not pedal at all. 


With its chunky, plus-sized tires, at first sight, the E3 Peak Plus seems like a cross between a hardtail mountain bike and a fat bike. It’s good looking: the mid-drive motor and removable, lightweight battery fit in nicely with the lines of the bike, making it look more like a standard mountain bike than other models. Unlike many mid-range e-bikes, it also comes in three sizes — handy if the usual one-size-fits-all approach doesn’t fit you.

We spent 45 hours on research, videography, and editing, to review the top choices for this wiki. With rechargeable battery-powered pedaling assistance, electric bicycles offer an increasingly viable alternative to fossil-fueled commuting, and e-bikes enable riders of various abilities to extend their range. But the street-legality of these hybrid machines remains a contentious issue, so be sure to check current state and local laws governing their operation before you hit the road.

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.


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.
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.
