Among the fastest long-range e-bikes we carry, the Eahora Romeo Pro III lists the longest range: 167–378 km on pedal assist from a 4,800 Wh battery, with a listed top speed of 80 km/h. Below, 10 of our long-range e-bikes with a listed top speed of 45 km/h or more are ranked by the best-case range each brand lists. Ride near top speed and the real distance falls sharply.
The fastest long-range e-bikes we carry, ranked by listed range
The ranking uses the longest pedal-assist range each brand lists for the bike as sold: the brand's best case, not our measurement. Speeds are the brands' figures too. Our long-range e-bikes collection has the full set; for speed alone, browse our fast e-bikes, sorted fastest first, or read our fastest e-bikes in Canada list.

Three pairs share the same listed battery, motors and range: the two TESWAYs, the Ridstar Q20Pro and YVY C20Pro, and the two Juliets. We left out bikes whose best figure needs optional extra batteries or isn't given for pedal assist, and bikes whose brand page gave conflicting figures.
In Ontario, Quebec, B.C. and Alberta, a bike rated above 500 W or assisting past 32 km/h falls outside the provincial e-bike rules, and every bike in this table lists a top speed above 32 km/h. Our e-bike laws guide covers each province.
Rules checked November 2026 on the official sources listed at the end. This is general information, not legal advice.
Why is listed range a best case?
On these spec sheets, the longest figure is for the gentlest riding. Jasion lists its Thunder Pro at up to 145 km in assist level 1 but 72 km in level 5, and says it measured them on a flat road in warm weather.
Throttle-only figures are lower again. Ridstar lists the Q20Pro at up to 290 km on pedal assist and up to 121 km on the throttle alone. Eahora lists 167–378 km on pedal assist for the Romeo Pro III and 113–122 km on the throttle.
FREESKY's Alaska Pro page sums it up: actual range "varies depending on rider weight, cargo, terrain, speed, pedal-assist level, weather, and battery condition". A figure with no conditions attached is a ceiling, not a promise.
How much range do you lose at high speed?
A lot, by the brands' own numbers. Taubik says its Recon covers up to 120 km in pedal-assist level 1, but around 60 km at top speed. Jasion's level 5 figure for the Thunder Pro is about half its level 1 figure.
At speed, air drag grows faster than any other force on a bike, so each fast kilometre costs more energy. Our guide to how fast e-bikes go explains the physics, and our battery range guide shows how to estimate your own range from watt-hours.
So when you plan fast rides, compare battery watt-hours as well as headline range. The Romeo Pro III's 4,800 Wh holds more than twice the energy of the Ridstar Q20Pro's 2,080 Wh.
What does a big battery add in weight and charging time?
Big packs come on heavy bikes. The Romeo Pro III lists 78.5 kg, the GT73 Pro 55.8 kg, the TESWAY X5 AWD and X7 AWD 54.0 kg each, and the Juliet 52.6 kg. The Swift Horse Ultra X-6E has the lowest listed weight in the table, at 37.6 kg.
That weight matters off the bike: on a car rack, up stairs or in an elevator. Check the listed weight against your rack's limit before you buy.
A bigger pack also takes longer to charge. On the same charger, charging time rises roughly in step with watt-hours, so the Romeo Pro III's 4,800 Wh would take nearly three times as long as the Swift Horse's 1,680 Wh. That is a worked example, not a measurement: check each brand's listed charging time, and plan full charges overnight.
What changes with two batteries?
Four bikes in the table reach their range with two packs. The GT73 Pro carries two 60 V, 18 Ah removable batteries, and the Ridstar Q20Pro and YVY C20Pro each carry two 52 V, 20 Ah packs. The Alaska Pro pairs an 18 Ah and a 27 Ah removable battery at 48 V.
The battery figures in the table are both packs combined. On the GT73 Pro and the Alaska Pro, both packs are removable, so you can carry each one inside to charge. When a listing quotes range with a second battery, check whether that battery comes with the bike or is sold as an option.
Five of the ten bikes here also list two motors; our dual-motor e-bikes collection has more.
How does cold weather change range?
Cold weather cuts range. Battery University explains that "cold temperature increases the internal resistance and lowers the capacity", and that the lost capacity comes back once the cell warms up. So a winter ride covers fewer kilometres than the same ride in summer.
Health Canada's battery safety page says to bring batteries to room temperature before using them, and not to charge in below-zero temperatures. With a removable pack, as on the GT73 Pro or the Alaska Pro, bring the battery inside after a cold ride and let it warm up before you charge it.
How to compare fast long-range e-bikes
- Watt-hours first: volts × amp-hours. The Romeo Pro III's 60 V, 80 Ah pack is 4,800 Wh.
- The conditions behind the range: assist level, rider weight, terrain and temperature. If none are given, treat the figure as the best case.
- The throttle-only figure, if you plan to pedal little. Every bike above that lists one gives a lower throttle number.
- Rated vs peak power: B.C. defines continuous power as "the power output that a motor can sustain for long periods of time without overheating". Peak is a short burst.
- Listed weight, for racks, stairs and elevators.
Frequently asked questions
What is the longest-range fast e-bike?
Of the bikes we carry with a listed top speed of 45 km/h or more, the Eahora Romeo Pro III lists the longest range: 167–378 km on pedal assist, from a 4,800 Wh battery. In our ranking, the TESWAY X5 AWD and X7 AWD come next, at up to 320 km. These are the brands' best cases, not measurements.
How far can a fast e-bike go at top speed?
Much less than its headline range. Taubik lists around 60 km at top speed for the Recon, against up to 120 km in assist level 1. To estimate your own range, divide the battery's watt-hours by the watt-hours per kilometre you use, as our battery range guide shows.
Do dual-battery e-bikes go farther?
They carry more energy, so in the same conditions they go farther. The Ridstar Q20Pro's two 52 V, 20 Ah packs total 2,080 Wh, and Ridstar lists up to 290 km on pedal assist. If a range figure needs an optional second battery, check whether it comes with the bike.
Does cold weather reduce e-bike range?
Yes. Cold raises a lithium-ion battery's internal resistance and lowers its capacity until it warms up again (Battery University). Health Canada says not to charge in below-zero temperatures, so bring the battery inside to warm up first.
