The e-bike with the longest advertised range is the Optibike R22 Everest, claimed at up to 300 miles on a single charge.
If you’re hunting for all-day distance, you’re in the right place. This guide compares standout long-range models, explains what those mile numbers really mean, and shows how to choose an e-bike that will still have juice when you roll back home. You’ll also see how speed, rider weight, terrain, and battery size swing real-world results.
Which E-Bike Has The Longest Range? Real-World Factors
On paper, the Optibike R22 Everest sits at the top with a headline figure of 300 miles from a massive 3,260 Wh dual battery. Close behind, FUELL’s Flluid-2 claims up to 225 miles from a 2,000 Wh twin pack. Delfast’s Top 3.0i lists up to 200 miles on a full charge. These numbers are possible at modest cruising speeds on flat ground, with a lighter rider and efficient assist. Push higher speeds, haul cargo, or climb a lot, and range drops fast.
How Manufacturers Calculate Range
Brands usually estimate range using steady cruising on level ground, low to medium assist, and a mid-weight rider. A helpful rule of thumb: watt-hours (Wh) divided by watt-hours per mile (Wh/mi) ≈ range. Casual cruising can dip to 10–12 Wh/mi. Fast riding and hills can push 20–25 Wh/mi or more. That’s why a huge battery doesn’t always deliver a huge day if you’re riding hard.
Why Battery Capacity Matters Most
Capacity is the tank. A 3,260 Wh pack can stretch much farther than a 625 Wh pack at the same pace. Motor tuning, tire choice, fit, and wind all play their part, but battery size plus your riding style set the ceiling.
Long-Range Standouts Compared (Early Picks)
Here’s a quick scan of headline claims from well-known long-range models. This first table keeps it broad and in-depth so you can spot patterns fast.
| Model | Advertised/Validated Range | Battery Capacity |
|---|---|---|
| Optibike R22 Everest | Up to 300 miles (low assist) | 3,260 Wh (dual 1,630 Wh) |
| FUELL Flluid-2 / 2S | Up to 225 miles (low assist) | 2,000 Wh (dual batteries) |
| Delfast Top 3.0i | Up to 200 miles per charge | ~3,456 Wh (72V, 48Ah) class battery |
| Trek Allant+ (Range Boost) | Up to ~120 miles (with extender) | 625 Wh + extender option |
| Specialized Turbo Vado 5.0 | ~62–75 miles typical (eco) | ~700+ Wh class (model-year dependent) |
| Giant FastRoad E+ EX Pro | Varies by assist and terrain | 500 Wh (compact EnergyPak) |
| Tenways Wayfarer | Up to ~85 miles | ~600–700 Wh class |
The takeaway: the longest-range claims live on bikes with very large battery packs and conservative cruising speeds. If your riding is mostly 15–18 mph on flat paths, you’ll get closer to those brochure numbers. If you’re riding fast Class 3 speeds, expect less.
E-Bikes With The Longest Range By Use Case
Riders chase range for different reasons. Pick the use case that fits your week and match battery size to pace.
Ultra-Distance Adventure
Optibike R22 Everest is built for huge days: a dual-battery frame, full-suspension chassis, and a torque-rich motor. It’s heavy and pricey, but the energy on tap is unmatched if you want a single-charge epic.
High-Capacity Commuter
FUELL Flluid-2/2S targets city range with two removable batteries and a slick mid-drive/automatic gearbox pairing. If your commute stacks miles, a two-kilowatt-hour pack keeps weekday charging to a minimum.
Speed-Capable Utility
Delfast Top 3.0i blends motorcycle-like hardware with pedals. It’s built to cover ground and carry speed. For paved distance with a throttle option (where legal), it’s a range heavyweight.
Big-Brand Everyday Distance
Trek Allant+ with Range Boost and Specialized Turbo Vado 5.0 aim at practical distance: school runs, fitness loops, and multi-errand rides. You won’t see triple-digit brochure numbers every day, but you’ll get reliable range with broad dealer support.
How To Read A Range Claim Without Getting Burned
Match Assist Level To Your Goal
Eco mode stretches miles. Turbo eats them. If you want max range, set a steady pace on a lower assist and keep cadence smooth.
Watch Your Average Speed
Aero drag ramps up quickly. That’s why riding at 16 mph can outlast 22 mph by hours on the same pack. If you need speed, plan for a mid-ride charge or a second battery.
Factor In Rider And Load
More weight means more watts. A backpack, panniers, or a child seat all nibble at the margin. The same goes for knobby tires, low pressures, and headwinds.
Use Battery Math To Sanity-Check
Take capacity in Wh and divide by a realistic Wh/mi for your route. Riding mellow at 12 Wh/mi on a 2,000 Wh bike? Roughly 165–170 miles is plausible. Riding brisk at 22 Wh/mi? Closer to 90 miles. This quick check keeps expectations grounded.
Can Real-World Records Help You Judge Range?
Yes—when they’re measured under controlled conditions. A well-known benchmark is a 2017 Guinness-verified run using a Delfast Prime that logged 228 miles on a single charge in a velodrome. That shows what’s possible when pace is steady and conditions are ideal. Street riding with stops, climbs, and wind will land lower.
Which E-Bike Has The Longest Range? Buying Checklist
It’s smart to set your target distance for a typical day, not a perfect track. Use this checklist to dial in your choice.
Range Target And Route Shape
- Daily distance: Add a 20–30% buffer for detours and cold weather.
- Terrain: Rolling hills eat watt-hours; select a bigger pack if your route climbs.
- Speed: Fast Class 3 commuting needs extra capacity.
Battery And Charging
- Capacity: 700–750 Wh is a good floor for 40–60 mile days at mixed speeds. Two kilowatt-hours and up are for mega-rides.
- Removability: Dual removable packs are handy if you can charge at work.
- Charger output: Higher-amp chargers cut downtime on tour.
Motor And Drivetrain
- Assist style: Mid-drives shine for big hills and efficient cadence.
- Gearing: A wide ratio helps you spin comfortably in eco without bogging down.
- Tires: Fast-rolling tires at proper pressure save watts on pavement.
Range Reality: What Riders Usually See
Most riders cruise in eco or a mid assist and blend flats with small climbs. On that kind of ride:
- 700–750 Wh packs often land in the 40–70 mile window.
- 1,000–1,250 Wh systems can push 80–120 miles if speed stays modest.
- 2,000+ Wh setups are the ticket when you want two or three long rides between charges, or a single very long day.
Legal Class And Speed Notes
Range ties to speed limits. Class 1 and 2 assist to 20 mph, while Class 3 assists to 28 mph. Higher assisted speed will lower range at the same battery size. If your rides lean fast, shop more capacity.

Charging And Care Tips That Preserve Range
Charge Planning
For multi-day rides, map coffee stops with outlets or carry a compact fast charger. If your frame accepts it, a second battery turns range anxiety into a non-issue.
Battery Health
Keep the pack cool and dry, aim for partial charges during daily use, and store around mid-charge for longer breaks. Tires at proper pressure and a clean drivetrain protect those amp-hours too.
Final Call: Which E-Bike Has The Longest Range?
For headline distance on one charge, Optibike R22 Everest leads with a 300-mile claim. If you want huge range in a commuter package, FUELL Flluid-2/2S offers up to 225 miles. For fast paved miles with stout hardware, Delfast Top 3.0i is the pick. Decide your pace, terrain, and daily distance first, then size the battery to match. That’s how you turn a big number on a spec sheet into reliable miles on the road.
