To find the serial number of your Opus bicycle, look under the bottom bracket of your bicycle. The serial number is an alphanumeric code on a sticker or engraved in the frame. 



For Electric bikes, the serial number will be located under the bottom bracket or along the downtube. It is also indicated on the small accessory box that was given to you by your Opus authorized dealer.

If you are looking for the serial number of the electric battery key, it is located on the small accessory box provided by your authorized Opus dealer. It is also on the key chain provided with your keys. Always keep the key chain and the spare key in a safe location. 



Transport Canada’s Motor Vehicle Safety Regulations include the following conditions for a vehicle to be classified as a power-assisted bicycle:

  • They must have pedals and be capable of being propelled by muscular power;
  • Less than 500W of electric motor output;
  • Incapable of providing further assistance above 32km/h;
  • The motor must not engage before you attain a speed of 3km/h.

All Opus electric bicycles conform to these conditions.

Each Canadian province sets its own highway traffic codes, and for the most part any power-assisted bicycle is treated just like any other bike. That is, no licence or insurance are required, and e-bikes are fully legal to use on public roadways. Note, however, that there are age restrictions in some territories, and helmet laws apply equally to e-bikes. We suggest that you look up your local regulations to make sure you’re fully compliant with the laws.

All Opus electric bikes feature “Pedal Assist,” which regulates the power delivery from the electric motor. Basically, sensors on the bike detect how hard you’re pedalling and control the motor’s output so it corresponds to your effort. The harder you pedal, the stronger the assist. The percentage of assist is controllable on the bikes. As a result, you’ll get greater range with a low level of assist, or use less effort with a high level of assist. When you stop pedalling, the sensors tell the motor to shut off to save power. The sensors also tell the motor when you’re travelling above 32 km/h, so that it will stop assisting you. While it is possible to ride faster than 32 km/h, you’ll be doing it by muscle power alone.

A battery’s charge can be looked at several ways, but the easiest number to consult is the Watt-Hour rating. The voltage of the battery, multiplied by the amp-hour rating, yields the watt-hour rating, or Wh. This gives you a rough idea of possible range.

The batteries on the Opus electric bikes are all charged from a standard 110v plug, using the supplied charger. Lights on the batteries indicate the state of charge so you can monitor its progress. Circuitry in the chargers prevent from over-charging the batteries.

As a general rule, you can expect an approximately 80% charge in two hours, and a full charge in three to four hours.

The answer is, “It all depends.” Many variables will affect the distance that you can ride on a charge. Rider and cargo weight, along with hilly terrain and strong headwinds, will all reduce the range. Refer to user manuals of each system for precise information.

Opus electric bikes are built with quality parts, and assembled and tested in our Montreal facility. Apart from the normal maintenance associated with a standard bicycle, the electric drive systems require the following basic maintenance:

-          Batteries need to be charged before long-term storage, and the electrical connections should be protected from contamination once the battery is removed. Batteries must be stored in a cool and dry place.

About the Opus electric bike systems:

-          The Opus electric bikes equipped with the Shimano STePS ebike drive system uses a proprietary drive unit that includes the motor, control unit and BB axle. The controls and display unit are connected with standard Di2 cables, and the system can be customized, updated and diagnosed using the standard Shimano e-tube program that connects to a computer via USB cables. Please see an authorized Opus dealer to service the Shimano STePS system.

-          The Pendix and Vittoria systems have two main components, the battery and the motor unit. A simple flashing light will indicate a problem with either unit, which can easily be serviced by an authorized Opus service location.

-          We have used both systems in extended testing, in inclement Canadian weather in all seasons, and they perform flawlessly. A note concerning winter use: Battery capacity is reduced in very cold weather, and the battery must be warmed up to above 10 degrees C before charging to avoid damage to the cells.
