Some power-on-demand only e-bikes can hardly be confused with, let alone categorised as, bicycles. For example, the Noped is a term used by the Ministry of Transportation of Ontario for e-bikes which do not have pedals or in which the pedals have been removed from their motorised bicycle. These are better categorised as electric mopeds or electric motorcycles.

The Haibike Urban Plus 2017 is made for the city, this 28 mph eBikes are ideal for escaping city traffic on bike paths. It features the all-new TranzX M25, It has shift detection which allows you to shift normally, your chain and sprockets will have more lifespan.

As a power electronics engineer I had intended designing and developing a torque assist bike so was surprised to find that a few manufacturers brought them out in Europe recently. I bought a Raleigh Vélo Cité with a 36V 10Ahr lithium battery. I would never use a throttle or cadence type unless I was infirm and I am sure that torque sensing pedelecs will become the norm as prices fall.

They Eliminate Much of the Heavy Lifting: Many e-bikes let you haul a load sweat-free. For example, Extracycles’ Bosch Electric Assist system helps you maintain an average speed of 15 mph, even when you’re bike is loaded with 400 pounds’ worth of rider and gear.

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 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.[44]

Laws governing who can ride electric bikes, and where, vary from state to state. In some places, you can ride cycle paths; in others, you cannot. You may need a license – and even insurance – and there may be age limits.

A custom designed electric trike with large plastic cargo bin at the back, three-speed internally geared hub can be shifted at standstill and is more durable than a traditional derailleur. Two mechanical disc brakes provide good stopping power, max speed limited to 7 mph in……

Looking in from the outside, this seems completely insane to me. I can’t get my head around the idea of a country (or group of countries) that doesn’t have a single definition and set of laws for types of motor vehicles. So where’s the trade body working to get this mess rationalised? How does the bicycle industry ever hope to expand the E-Bike market if the rules are different in every state and even city and town? There’s a ot of money to be from consistency and standardisation.

You gotta be kidding. What’s the point of having the bike if I have to slow down to a walking pace to avoid some idiotic, brainless move? I’ll just trade it in for a rusty Schwinn and then stop biking altogether because that’s stupid.

Torque is a consideration, but actual figures are rarely quoted by e-bike makers. Owners will frequently comment on whether their electric bike offers plenty of torque or lacks it, but these comments need to be taken in context. Road conditions, as well as the weight of the rider, have a big impact.

The part that confuses me is the “saddle”. Recumbent trikes do not have the typical bicycle saddle seat. They have a nice comfy fully supportive seat. Some are like bucket seats. So then I’m thinking, would it be a moped under WA law?

The multi-speed option is equipped with a  Shimano Altus 7-speed derailleur and shifter system. It adds about 2 lbs (1 kg) of weight and requires occasional BASIC maintenance. However, it provides the benefit of incline and long distance riding without the need for electric assist.

  Finally we are getting somewhere.  I have a bicycle, check.  It has an electric motor, check. I weighed it, and it was 80 pounds, check.  When I rode it, it went 23-MPH.  Whoops!  “Cannot attain a speed of more than 20-MPH”

Persistence Market Research in September 2017 predicted a global market growth of 4.7% CAGR during the period 2017-2022.[37] Asia-Pacific excluding Japan (APeJ) is a lucrative region and is expected to show high market share by the end of 2022.

In this chapter, it tells you how to operate the bicycle or in this case e-bicycle.  In most cases, there is little variation in this area from state to state.  All the usual stuff about having at least one hand on the handlebars, having a light at night, riding as far to the right as can be done safely, etc.  In nearly all states, it will clearly state that bikes obey traffic laws, such as speed limits, stop signs etc.  Just because you are allowed 20-MPH on the ebike you can’t ride though the 15-MPH school zone at 20-MPH.  You’d think this would be pretty obvious, but far too many bike riders think that no license required means no laws apply.  It’s not the case.  But it’s true that cops may ignore your breaking the law on a bicycle. Or…they may not.  Do you feel lucky?

E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.

“Yamaha is a well-known and respected brand, but the market is already pretty saturated with manufacturers,” Flagg said. “This is a very competitive space. The opportunity for a manufacturer to have a huge impact has probably passed.”
