Electric bikes are one of the best options for riders with bad knees or joint pain because the motor carries the load your joints can't. The pedal-assist system lets you keep a smooth, steady cadence without forcing power through painful knees, and step-through frames remove the awkward leg-swing that aggravates hips and lower backs. For most arthritis sufferers, a step-through e-bike with a mid-drive or torque-sensing hub motor is the most comfortable, confidence-boosting way to cycle again.
This guide explains why e-bikes help, what to look for in a frame and motor, and lists five bikes from Bike Yard Online (BYO) that are particularly well-suited to riders managing knee arthritis, cartilage damage, or general joint pain.
Why E-Bikes Work So Well for Sore Knees and Arthritis
Cycling is already one of the best exercises for painful knees. It is low-impact, which means there is almost no jarring load through the joint compared with walking or running. A 2024 study of the Osteoarthritis Initiative cohort, published in Medicine & Science in Sports & Exercise, found that people who cycled at any point in their lives were around 17% less likely to develop frequent knee pain and 21% less likely to develop symptomatic knee osteoarthritis than non-cyclists.
An e-bike takes that benefit further. A pedal-assist motor adds power in proportion to how hard you press the pedals, so the resistance your knees feel stays light and controllable. A pilot study published in Applied Sciences measured muscle activity in riders with knee osteoarthritis across different e-assist levels. Peak load in the quadriceps (rectus femoris and vastus medialis) and hamstrings was lower at high-assistance settings than at no assistance, confirming what riders already know: the higher the assist level, the less work the knee has to do.
The charity Versus Arthritis lists cycling among the activities most commonly recommended for people with osteoarthritis, alongside walking and swimming. An e-bike simply keeps you on the bike for longer and lets you ride on days when a regular bike would be too much.
Step-Through Frames Are Almost Always the Right Choice
If your knees or hips are painful, the single most important frame feature is the absence of a top tube. A step-through frame (sometimes called a low-step or open-frame) lets you walk through the bike instead of swinging a leg over the saddle. That one design change removes the move most likely to trigger a knee flare-up or send you off balance when mounting.
Step-through frames also make it easier to stop at junctions without dismounting fully. You can simply put one foot down while still seated, which is a big confidence boost for riders who worry about catching a leg on a crossbar. BYO stocks a wide range of step-through electric bikes, and for most riders managing joint pain it is the default starting point.
Mid-Drive or Hub Motor - Which Is Kinder on Your Knees?
The motor type matters almost as much as the frame. The two options on road-legal EAPC e-bikes are hub drives (motor in the rear or front wheel) and mid-drives (motor mounted at the cranks).
A mid-drive motor pushes the chain, so its power is multiplied through the gears. That means higher effective torque when you need it - usually up a hill - without you having to stamp on the pedals. Hub drives deliver their torque directly to the wheel, which is smoother on flat ground but can leave you grinding up hills because the motor cannot use your gears.
For arthritic knees, the rule of thumb is simple: if you live somewhere hilly, pick a mid-drive. If you live somewhere mostly flat, a well-specced hub drive with a torque sensor (which responds to pedal force rather than just pedal motion) is usually enough. We cover the full trade-off in our guide to hub motor vs mid-drive e-bikes.
5 Best Electric Bikes for Bad Knees and Joint Pain
Each of these bikes has either a step-through frame, a mid-drive motor, or both. All are EAPC-compliant (250W continuous motor, 15.5 mph assist cutoff), all come with BYO's UK-wide delivery and technical support, and all sit in a price range that makes sense for a bike you'll ride long-term. No more than two are from the same brand.
1. Ampere Deluxe Step Through Hybrid 250W
A proper entry point for riders who want a comfortable, confidence-first e-bike. The Deluxe Step Through comes in two wheel sizes (26" for shorter riders and 700C with front suspension for taller riders), uses a smooth rear-hub motor, and has an upright riding position that keeps pressure off your wrists and lower back. The low step-over is unusually low, which is what makes it such a popular pick for riders in their 50s, 60s and 70s managing knee issues.

2. Ampere Deluxe Pro Mid-Drive Step Through 250W
The Deluxe's bigger sibling. Same friendly step-through frame, but with a Motinova mid-drive motor producing up to 90Nm of torque on the 26" model. If you want the gentle mounting of a step-through and the hill-climbing ease of a mid-drive in one bike, this is the shortlist. Torque sensing means the assist responds to how hard you pedal, so you can keep a light, consistent cadence that is kind to arthritic knees.
3. Dawes Spire 2.0 Cues Low Step 250W
A classic British name doing what Dawes do well - a sensible, robust hybrid with a low-step frame. The 2026 spec uses Shimano Cues 1x9 gearing and Shimano MT200 hydraulic disc brakes, which is a strong drivetrain and brake combination for the money. The low step makes mounting easy, and the upright geometry keeps you in a relaxed position that doesn't put strain on your neck or shoulders. A strong choice for riders with mild-to-moderate knee pain who ride mostly on the flat.

Setting Up Your E-Bike to Protect Sore Knees
Buying the right bike is only half the job. A few small adjustments make a big difference for anyone cycling with arthritis.
Raise the saddle. Most knee pain from cycling comes from a saddle that is too low. When seated, the knee should be slightly bent (around 25-30 degrees) at the bottom of the pedal stroke, not fully bent. Too much bend crushes the kneecap against the thigh bone.
Spin, don't push. Aim for a cadence of 70-80 RPM rather than a slow, heavy push. A lower gear and faster legs is gentler on the knee joint than a higher gear and slow grinding pedals. The motor and the gears are there to keep the cadence comfortable - use them.
Use higher assist on hills. There is no prize for pedalling an e-bike up a hill in Eco mode. If a climb is hurting your knees, switch to Sport or Turbo. You'll still be pedalling, still getting exercise, just without the joint load.
Fit flat pedals unless you're experienced with clips. Clipless pedals lock your foot into a fixed position, and if your knees don't align perfectly they'll protest. Flat pedals with grippy pins let you float your foot naturally.
Frequently Asked Questions
Is cycling good for arthritic knees?
Cycling is widely recommended for osteoarthritis of the knee because it is low-impact, keeps the joint moving through its range of motion, and strengthens the quadriceps and hamstrings that support the knee. Research from the Osteoarthritis Initiative found lifetime cyclists had less frequent knee pain than non-cyclists, and UK charity Versus Arthritis lists it among its recommended activities.
Are electric bikes easier on knees than regular bikes?
An e-bike's motor lets you keep a light, steady cadence rather than grinding up hills or into headwinds, which is what often triggers knee pain on a regular bike. A peer-reviewed pilot study in Applied Sciences measured lower quadriceps and hamstring load in knee-osteoarthritis riders using higher e-assist levels, confirming the knee works less at higher assistance.
Should I buy a step-through or crossbar e-bike if I have knee pain?
A step-through frame is almost always easier on painful knees and hips. You walk through the bike instead of swinging a leg over a top tube, which removes the mounting movement most likely to cause a flare-up. Crossbar frames only make sense for knee-pain riders who have good mobility and prefer the stiffer feel.
Is a mid-drive or hub motor better for bad knees?
Mid-drives are generally better if you live somewhere hilly, because they channel power through the gears and give you higher torque on climbs without forcing you to push harder on the pedals. A torque-sensing hub motor is smooth and sufficient on mostly flat routes. The Ampere Deluxe Pro in our list is a mid-drive; the others are hub drives.
How high should the saddle be on my e-bike?
With your heel on the pedal at the bottom of the stroke, your leg should be almost straight. When you move the ball of your foot onto the pedal for normal riding, your knee will have a 25-30 degree bend, which is the sweet spot for knee health. A saddle that is too low is the most common cause of cycling knee pain.
Can I ride an e-bike with a knee replacement?
Many riders with knee replacements cycle happily on e-bikes once their surgeon clears them, usually around 6-12 weeks post-op. The low-impact nature of cycling and the motor's ability to reduce pedal effort make e-bikes particularly suitable. Always check with your consultant or physiotherapist before riding after surgery.
Is using the throttle better for sore knees than pedalling?
Throttles exist on a minority of UK road-legal e-bikes and only provide assistance up to 6 km/h without pedalling. They are useful for getting moving from a standing start, which is the moment knee pain is often worst, but relying on the throttle for the whole ride skips the low-impact exercise that is actually good for the joint.
How much should I expect to spend on a good e-bike for bad knees?
A well-built step-through e-bike with a torque-sensing motor, hydraulic brakes, and reliable components starts around £1,200 and runs up to £2,000.
Key Takeaways
- Choose a step-through frame to remove the leg-swing that most commonly aggravates knee and hip pain when mounting.
- Pick a mid-drive motor if you ride hills; a torque-sensing hub motor is kinder on the knees than a cadence-only hub motor on flat terrain.
- Set your saddle high enough that your knee has only a slight bend at the bottom of the pedal stroke - low saddles cause most cycling knee pain.
- Use higher assist levels on climbs rather than grinding up in Eco mode; you still pedal, you just protect the joint.
- For most BYO customers, the Ampere Deluxe Pro (mid-drive, hilly routes) or the Ampere Deluxe Step Through (hub-drive, flat routes) are the strongest all-round picks.
