hoarding your gas powered motor bike. 2035 is the last ...

A modern EV charged by the grid is overall more efficient at the system level even IF the grid is fed by a coal-fired plant of decent efficiency (and there is no more coal-fired power generation in Ontario).

A central thermal power plant can be operated close to its best-efficiency conditions almost all the time. A decent coal-fired generating station has a thermal efficiency (energy content of coal in, to energy content of electricity out) of 40% or a bit more. A combined-cycle natural-gas-fired plant (uses a gas-turbine "topping" cycle then the exhaust heat operates a steam-turbine "bottoming" cycle) can have a thermal efficiency of 55% - 60%. Accounting for transmission losses to get to the EV charging point plus the charge-discharge losses at the battery plus losses within the inverter and motors still means the combined system "fossil fuel to wheels" will be in the 30% range for coal-fired or beyond 40% for natural-gas-fired combined-cycle generation.

A good internal-combustion engine can have a 40% thermal efficiency at its best operating point ... but the engine in your motorcycle is not the engine in a Toyota Prius. Low 30s are more likely. And ... That's at the best operating point - probably somewhere in the vicinity of 50% of rated RPM and 75% of rated torque. Most combustion-engine-powered vehicles spend very little operating time in the vicinity of that best operating point. They spend an awful lot of time idling (0% efficiency), and cruising around at part load (poor efficiency). A 200 hp engine has a poor efficiency when it is only producing the 10 hp that it takes to trundle along a country road or putter around town.

EVs don't have that situation. If you're stopped in traffic, the powertrain is drawing no battery power. The powertrain efficiency tends to be +/- 90% over a very wide operating range regardless of instantaneous power demand. And ... regenerative braking. No can do with a non-hybrid combustion-engine vehicle.

Most automotive-scale smaller EVs use around 20 kWh per 100 km, but that is high-grade electrical energy that can be used to make mechanical power with +/- 90% efficiency. Comparable car uses about 7 or 8 L/100 km; one litre of gasoline = 0.74 kg = approx 10.3 kWh of chemical energy but this can only be used at the brake-thermal-efficiency in actual in-service operating conditions to convert it to mechanical power. If the car is using 7 L/100 km that's 72 kWh of chemical energy input per 100 km. That implies a tank-to-wheels efficiency in the combustion engine vehicle of around 25% compared to 90% for the EV ... that's about right for a good one under good operating conditions. Stuck in city traffic, it's going to be a lot worse for the combustion-engine vehicle, and the EV will still be around 90% but with lower power demand because of the lower speed and regenerative braking.

The pros and cons of electric motorcycles and gas ...

If you love riding motorcycles, electric-powered and gasoline-powered bikes are both fun to drive and are the top-used mode of alternative transportation in the world. Nonetheless, each has its pros and cons which a rider has to consider when making a purchase, especially since the electric motorcycle is making quite a comeback. Let’s take a look at the pros and cons of each to see how a biker can make a decision which is best for him or her.


Pros of electric motorcycles


The following are the pros of electric motorcycles.

  • They are more environmentally friendly. The fact that electric motorcycles are more environmentally friendly than gas motorcycles is a definite plus. With fewer greenhouse emissions, it reduces air pollution and diminishes the negative effects of global warming.

  • They are very easy to operate. Electric motorcycles are easy for younger and older drivers who love it’s ease of operation.

  • They are safer than gas motorcycles. Electric motorcycles have a lot of safety features that give people of all ages a sense of security. You don’t have to learn how to change gears or use a clutch, and you don’t have to worry about gas or oil. Also, it takes a lot less physical effort to drive one.


Cons of electric motorcycles


 The following are the cons of electric motorcycles.


  • They cost more than gas-motorcycles. One of the great disadvantages of electric bikes is their cost in electricity. You can guarantee it will make your electric bill go up. In addition, replacing a battery is costly.

  • They are short-range cycles. Don’t plan a long road trip with electric motorcycles. They are designed for short trips. Also, when needed, it takes a while for them to recharge.

  • Their battery life is limited. Unfortunately, maintenance-free electric batteries don’t last all that long. Logically, the more you drive it, the sooner you will have to charge and replace it. You also have to take care not to over-charge the battery, or you could do permanent damage to it. New technology is currently being studied to manufacture longer-lived batteries.


Pros of gas motorcycles

Most motorcycle riders prefer their gas powered motorcyclesgas powered motorcycles, and here’s why.

  • They are faster. There is no doubt about it – gas motorcycles are faster, have better suspensions, and are definitely capable of long-range road trips.

  • They have a higher resale value.Unlike their electric counterparts, gas motorcycles are more in demand so finding a buyer is easier. They also have a higher resale value and a well-maintained one can garner a good price.

  • They are less expensive.Gas is plentiful, easy to find and less expensive than the electricity costs of electric bikes.

Cons of gas motorcycles

Even ardent fans of gas motorcycles have to agree there are some disadvantages to them.

  • They weigh a lot more than an electric motorcycle. Although they do come in different weights and sizes, a gas motorcycle requires effort to move it around and requires specific ability and strength to maneuver it.

  • Maintenance can be costly. If you are a self-made mechanic, you can maintain your gas-bike by yourself. If not, you will have to use the services of a private mechanic or dealer and repairs and maintenance can be costly. Because of safety reasons, you definitely have to keep your bike in top-running condition, so good maintenance is a must.

  • They are less environmentally friendly. Studies show that gas motorcycles are bad polluters, having much worse emissions than do electric motorcycles. In addition, the chemicals produced by the gas used are harmful to humans and other life forms. The fumes can cause illness and harm to the individual inhaling them.


Although gas motorcycles are more popular, the rise in electric motorcycles is significant. Choosing which type of bike is good for you is going to be a matter of preference, based on the pros and cons of each. Whichever you choose, make sure to stay safe on the road, wear protective gear and stay aware of all of the traffic around you.
