An e-bike is real exercise. It is a little gentler per minute than a regular bike, and that small gap matters less than most people expect.
People ask us the same thing before they buy: if the motor is helping, am I still working? The honest answer has two halves. Minute for minute, you work somewhat less on an e-bike than on a conventional bike. Across a week, though, many riders end up doing more, because an e-bike is easier to start and easier to repeat.
This guide covers what published research found about heart rate and fitness, how that lines up with the CDC's weekly activity targets, and how to set up your rides so they feel like a workout when you want one. We also point out where the evidence is thin, because most e-bike studies are small and short.
One note first: this is general information, not medical advice. If you are coming back from an injury or live with a heart, lung, or joint condition, check with your clinician before changing how much you exercise.
What the research says about e-bike intensity
Most studies put the same rider on an e-bike and on a conventional bike, then compare heart rate and oxygen use. Two systematic reviews give the clearest picture.
Heart rate and oxygen use
A 2022 meta-analysis by McVicar and colleagues in the Scandinavian Journal of Medicine & Science in Sports pooled 14 studies with 239 participants. With moderate electrical assistance, riders had a heart rate about 11 beats per minute lower than on a conventional bike (a mean difference of 11.41 bpm). Oxygen uptake was lower too. The MET estimate, which rests on only four studies, came out about 0.83 lower. A MET is a unit of effort where 1 equals sitting at rest.
Compared with walking
A 2018 systematic review in the International Journal of Behavioral Nutrition and Physical Activity covered 17 studies. It found moderate evidence that e-cycling is at least moderate-intensity activity, lower than conventional cycling but higher than walking. It also found moderate evidence that e-cycling can improve cardiorespiratory fitness in people who were physically inactive. Evidence for metabolic and psychological outcomes was inconclusive.
What to hold loosely
The McVicar team rated 12 of the 14 studies as weak in quality, and individual studies enrolled between 3 and 33 people. Terrain, assist level, and rider fitness differed from study to study. The 2018 reviewers asked for long-term studies with stronger designs. A fair summary: short-term results are consistent and encouraging, and long-term proof is still missing.
How e-bike riding compares with the CDC activity targets
The CDC's adult guidelines call for 150 minutes of moderate-intensity activity a week, or 75 minutes of vigorous activity, or an equivalent mix. They also ask for muscle-strengthening activity on at least 2 days a week.
What moderate intensity feels like
The CDC defines moderate intensity as 3 to 5.9 METs and vigorous as 6 METs or more. The talk test is the easy version. At moderate effort you can talk but not sing. At vigorous effort you can say only a few words before you need a breath. On a 0 to 10 effort scale, moderate sits around a 5 or 6.
What 150 minutes looks like
Thirty minutes a day on five days gets you there. So does a commute of 15 minutes each way, five days a week. If that sounds like your week, our complete e-bike commuting guide covers the practical side, including bike choice, costs, and charging at the office.
A rough calorie estimate
A common approximation is METs times body weight in kilograms times hours. As an illustration only, a 180 lb (82 kg) rider at 5 METs for 30 minutes uses about 205 calories (5 times 82 times 0.5). At 4 METs, the same ride is about 164. Real numbers vary with the rider, the terrain, and the assist level, so treat this as a ballpark.
What a bike does not cover
Cycling works the legs well, but the CDC's strength target covers all the major muscle groups. Add two short sessions a week of squats, push-ups, or whatever strength work you already do.
How to ride an e-bike for a better workout
Choose your assist level on purpose
Lower assist levels make you do more of the work, and higher levels let the bike do more. Use the higher levels for headwinds, steep starts, and recovery. Drop down when you want effort. Lower levels also stretch your battery, which our guide to real-world e-bike range explains in detail.
Pedal assist versus throttle
Class 2 e-bikes, the category Snapcycle sells, have both a throttle and pedal assist, with motor assistance ending at 20 mph. Pedal assist only helps while you pedal, so your legs stay in the work. Riding on the throttle alone is much closer to coasting. Use the throttle to pull away from a light or take a short breather, and use pedal assist for the stretch you want to count as exercise.
Use hills, wind, and soft surfaces
Climbs and headwinds raise your effort even with assist. Soft surfaces do too. Sand takes real leg work, and our guide to riding a fat tire e-bike on sand covers how to handle it. A route with a few gentle rises gives you a better workout than a perfectly flat one, without making the ride miserable.
Try simple intervals
Ride at your usual assist for five minutes, drop one level for two minutes, then return. Or pick a landmark ahead and push to it before easing off. Keep most of the ride conversational and spend short stretches working harder.
Watch the heat
Hot weather pushes your heart rate up at the same effort, so ease off and drink water on summer rides. Heat is hard on batteries too, which we cover in how to protect your e-bike battery in summer heat.
Who gets the most out of e-bike exercise
People who are new to exercise or coming back to it
The 2018 review's fitness finding applied to physically inactive people. An e-bike lets you begin at an effort you can sustain, then add more as you get fitter.
Riders with hills, distance, or sore joints
Assist takes the sting out of climbs and long routes, so rides that might have put you off become realistic. Cycling is seated and low-impact, which is why many people with sore joints prefer it to running. If you have joint pain, ask your clinician what is right for you.
Commuters who want to arrive in good shape
Because heart rate runs lower for the same trip, many commuters find it easier to ride to work and still feel fresh on arrival. You still collect the activity minutes, and you can choose the assist level that fits the day.
Why riding more often can beat riding harder
A randomized crossover study of 101 German office workers, published in the International Journal of Environmental Research and Public Health, had people try both a conventional bike and an e-bike. Average heart rate on the e-bike was lower, 109 versus 118 bpm. But riders logged about 174 minutes a week on the e-bike, against about 99 on the conventional bike. Slightly lower intensity over many more minutes can add up to more total activity. It was a short trial, so it shows what people did in the first weeks, not what they do for years.
Make the easy ride the default
The best workout is the one you repeat. Tie rides to things you already do, like the commute, a coffee run, or a weekend errand, and the exercise comes along with them. Start with two or three rides a week of 20 to 30 minutes and add from there.
A simple four-week ramp
- Week 1: three rides of about 20 minutes on flat routes at a middle assist level.
- Week 2: three rides of 25 to 30 minutes, dropping the assist one level on the flats.
- Week 3: four rides of about 30 minutes, with one route that includes a hill.
- Week 4: four or five rides of about 30 minutes, with short intervals on one of them. Five rides of 30 minutes reaches the 150-minute mark.
Adjust it to how you feel. Skipping a day to recover is part of the plan.
Frequently asked questions
Does an e-bike count as exercise?
Yes. Reviews of the research find that e-bike riding is at least moderate-intensity on average, lower than conventional cycling but higher than walking. How hard you work depends on the assist level, the terrain, and how much you pedal.
Do I burn fewer calories on an e-bike than on a regular bike?
Per minute, usually a little fewer. The 2022 meta-analysis found lower heart rate, oxygen uptake, and METs on e-bikes, but it did not find a statistically significant difference in total energy expenditure, and the studies were small. Riding longer or more often can close the gap.
Can an e-bike help me lose weight?
The evidence on metabolic outcomes is inconclusive so far. Weight depends on total activity, food, and sleep. What an e-bike can do is make regular riding easier to keep up. For personal goals, talk with your doctor or a dietitian.
Should I use the throttle?
Use it when it helps, such as pulling away from a stop or taking a short rest. If exercise is the goal, ride mostly on pedal assist, since the throttle works without pedaling.
How do I know I am riding hard enough?
Use the talk test. If you can talk but not sing, you are in the moderate zone the CDC describes. If you can only say a few words at a time, you are working vigorously. Adjust the assist level to move between the two.
