The Guinness-verified record belongs to the Delfast Prime, which covered 228 miles on a single charge under controlled conditions.
If you’re here to settle which electric bike really goes farthest per charge, you want a clear, tested answer—not marketing fluff. The short version: a Delfast Prime set the official record at 228 miles on a single charge on a velodrome, certified by Guinness World Records. Beyond that lab-like result, big-battery adventure models claim even longer figures in the real world with strict speed caps and steady pedaling. This guide lays out the verified winner, the strongest long-range claims you’ll see in stores, and the simple math you can use to predict your own range.
Which Electric Bike Has The Highest Mileage? Facts That Matter
First, a quick definition. When people ask “which electric bike has the highest mileage,” they almost always mean range per full charge. That’s the distance an e-bike can travel before its battery needs the charger again. The official, measured answer comes from a track test with no traffic, no hills, and a steady pace. Street riding brings wind, climbs, cold mornings, and stop-and-go that can cut range fast. So we’ll give you both: the verified record holder and the strongest production claims you’ll see today.
The Shortlist: Record Holder And Big-Battery Contenders
Here are well-known long-range names you’ll run into, sorted by the basics that drive distance: battery capacity and stated range. Use this as a quick scan before we unpack how these numbers play out on actual roads.
| Model (Category) | Battery (Wh) | Claimed/Verified Range (mi) |
|---|---|---|
| Delfast Prime (Record Setup) | ~3,000+ | 228 (Guinness verified) |
| Delfast Top 3.0 / 3.0i (Off-Road Style) | ~3,300–3,500 | Up to ~200 (claimed) |
| Optibike R22 Everest (Adventure) | 3,260 (dual) | Up to ~300 at ~15 mph (claimed) |
| Segway Xyber (Moped-Style) | — | Up to ~112 (claimed) |
| Segway Xafari (City/Trail) | — | Up to ~88 (claimed) |
| Lectric XP4 750 (Folding) | ~840 (17.5Ah at 48V) | Up to ~85 (claimed); ~50 seen in testing-style reviews |
| TENWAYS Wayfarer (City) | — | Up to ~85 (claimed) |
Two takeaways jump out. First, the record is a Delfast Prime on a consistent track. Second, adventure models with massive batteries post the largest claims in store listings and media previews. Those claims usually assume low speed, steady cadence, and favorable weather. Your daily loop will vary.
Electric Bike With The Highest Range: Real-World Picks
If you want the longest distance today without building a custom pack, you’re shopping in the “big battery” corner. These bikes trade weight and price for watt-hours (Wh). More Wh equals more stored energy. The trick is turning that energy into miles efficiently, which depends on speed, grade, wind, tire choice, and how much you pedal.
Why The Delfast Prime Holds The Crown
The Delfast Prime completed 228 miles on a single charge under a controlled track test, certified by Guinness. That’s an apples-to-apples answer to which setup has gone farthest on one charge with independent verification. The protocol trims the wild cards—steady speed, flat surface, no traffic—so the number stands as a clean benchmark you can trust.
Where High Claims Fit (And When They Hold Up)
You’ll see adventure bikes with monster packs—like dual-battery builds—touting 250–300-mile figures. These numbers often come with fine print: modest cruising speed (around 15 mph), smooth terrain, and consistent pedaling for long stretches. Hit a headwind, climb a ridge, or bump speed to the mid-20s, and the math changes fast. Treat big claims as “best case with patience” rather than what you’ll see blasting across town.
How To Estimate Your Own Range In Two Steps
Skip the guesswork with a short method you can use for any e-bike. You just need battery size in watt-hours and a realistic energy burn per mile for your riding.
Step 1: Grab Battery Watt-Hours
Watt-hours (Wh) = volts × amp-hours. A 48V, 17.5Ah pack is ~840Wh. A 72V, 48Ah pack is ~3,456Wh. Bigger Wh means more stored energy to turn into miles.
Step 2: Pick A Realistic Wh-Per-Mile Number
For city riding at 15–18 mph with pedal assist, many riders average around 15–25 Wh/mi. Heavier bikes, higher speeds, fat tires, hills, or strong throttle use can push that to 30–40 Wh/mi or more. Cold weather can shave range, too. With that in mind:
- 840Wh pack at 20 Wh/mi → ~42 miles; at 30 Wh/mi → ~28 miles.
- 3,300Wh pack at 20 Wh/mi → ~165 miles; at 30 Wh/mi → ~110 miles.
That simple math explains why record attempts pick steady, moderate speeds. Energy burn per mile collapses when you crank up pace or tackle big climbs.
What “Highest Mileage” Means For Different Riders
“Highest” isn’t one size fits all. If your commute is flat and slow, you can stretch range on a middling battery. If you tour with camping gear, only a huge pack gets you past 100 miles without mid-day charging. Use the scenarios below to match style to the right battery class.
Long Commute, Flat Terrain
Pick a mid-capacity pack (700–1,000Wh) with efficient street tires and a torque sensor. Keep cruising speeds near the low-to-mid teens in Eco/Low assist. You’ll likely beat many marketing ranges because you’re riding in the happy zone for efficiency.
Mixed City And Trail
Go for 900–1,200Wh and tires that roll well on pavement but grip on dirt. Expect 40–70 miles with measured pacing. Big hills? Budget extra Wh or plan a top-up stop.
Adventure Touring And Bikepacking
This is where ultra-large packs shine. Two-to-three kilowatt-hours gives you the freedom to ride out all day at low speed with room for climbs and wind. Keep your expectations honest: loading bags, wider tires, and soft surfaces all raise Wh-per-mile.
Seven Levers That Change Your Range
You can squeeze far more miles from the same battery by trimming losses. Small tweaks stack up fast over a full charge.
Speed
Air drag grows quickly as you go faster. A drop from 22 to 16 mph can cut Wh-per-mile dramatically. If distance is the goal, ease off the throttle and let cadence do the work.
Assist Mode And Cadence
Lower assist with a steady spin makes every watt count. Short, punchy surges burn energy without adding meaningful distance.
Tires And Pressure
Slicker tread and proper inflation reduce rolling losses. Knobbies on pavement eat range. If you split time between surfaces, consider a fast-rolling hybrid tread.
Terrain And Wind
Hills and headwinds raise Wh-per-mile. Plan routes that shield you from wind or trade a small detour for a flatter profile when range matters.
Temperature
Cold packs deliver less. Store and charge indoors when possible. Start rides with a warm battery, then manage assist conservatively outside.
Weight
Rider, cargo, and even heavy accessories change the math. Trim what you don’t need for long rides.
Drivetrain Efficiency
A clean chain and aligned brakes sound boring but they’re free miles. Brake rub can cost you minutes of charge without you noticing.
Range Killers And Quick Fixes
Here’s a compact cheat sheet you can save. Each factor moves the needle; combine two or three and you’ll notice the difference by lunchtime.
| Factor | Effect On Range | What To Do |
|---|---|---|
| High Cruising Speed | Large drop via aero drag | Cap speed; draft; pick calmer streets |
| Cold Battery | Reduced output and capacity | Charge and store indoors; start warm |
| Soft, Knobby Tires | Higher rolling resistance | Use efficient tread; check pressure |
| Steep, Frequent Climbs | Spikes Wh/mi | Shift early; smooth cadence; reroute when range matters |
| Stop-Start Riding | Wasted bursts | Anticipate lights; carry momentum safely |
| Extra Cargo | More weight to move | Pack light; mount bags centrally |
| Poor Maintenance | Hidden drag | Clean/lube chain; align brakes; true wheels |
Real Answers To Two Common Reader Questions
Is The Record Relevant To Daily Riding?
Yes, as a benchmark. A velodrome run removes variables so we can say, with confidence, what’s been achieved on one charge under consistent conditions. Street range will be lower unless you mimic that steady setup.
Why Do Some Bikes Claim 250–300 Miles?
Because they carry huge batteries and the test pace is gentle. Drop your cruising speed, pedal steadily in a low assist mode, and keep terrain smooth. Under those rules, big-battery bikes can creep into triple digits.
Buying Tips If Range Is Your #1 Priority
Start With Watt-Hours, Not Motor Watts
Motor power influences feel and hill starts. Battery capacity determines miles. When you’re comparing two bikes, divide the pack size by a realistic Wh-per-mile number from your riding style to get a fair estimate.
Favor Torque Sensors For Efficiency
Torque-sensing assist feeds power in proportion to your pedal force, which encourages a smooth cadence and better economy. Cadence-only setups can surge and waste energy at the same speed.
Check The Gearing
Long-range rides live in the mid-teens for speed. You want a gear range that lets you spin comfortably there without over-spinning on flats or grinding on rises.
Mind Real Charging Options
Can you stash a charger at work? Does the pack remove easily? Is there a fast-charge accessory your manufacturer supports? Practical charging beats chasing the biggest possible battery for many riders.
The Final Word On “Highest Mileage”
For a single-charge distance that’s been witnessed and logged, the Delfast Prime holds the confirmed record. If you need a production bike that can go as far as possible with careful pacing, the adventure class with multi-kilowatt-hour packs is where you’ll find the top claims. Keep your expectations tied to speed, weather, and terrain, and use the Wh/mi math to predict your own number before you buy.
Use The Keyword In Context (For Readers Who Search This Way)
People often type the exact phrase which electric bike has the highest mileage? when they want a single, trusted winner. The certified answer is the Delfast Prime at 228 miles on one charge on a track. If you’re comparing store models, treat big numbers as best-case scenarios and apply the range math above to your route.
Another common search is which electric bike has the highest mileage? for commuting. In that case, a mid-capacity pack with efficient tires and a torque sensor can beat many catalog figures at calm speeds. If weekend tours are on the menu, a two-to-three-kilowatt-hour setup gives you breathing room for hills, wind, and gear.
One More Thing: Source Check For Peace Of Mind
If you want an official write-up of the record, read the Guinness World Records entry for the greatest distance on a single charge. It names the rider, the venue, and the model used. That’s the standard everyone cites when talking about the furthest an e-bike has gone on one battery.
