Published weight, capacity and class, side by side
The “Not published” cells are the useful part of this table. Two of the six bikes here will not tell you what they weigh, and four of the six will not tell you what class they are.
| Bike | Published weight | Battery | Removable pack | Class | Published load |
|---|
| Jasion EB5 | 49.6 lb | 360 Wh | Yes - charges off the bike | Not published | Not published |
| isinwheel U3 Folding | 51.9 lb | 281 Wh | Yes | Not published | Not published |
| Retrospec Chatham Rev | 58 lb | 360 Wh | Yes | Class 2 (20 mph) | 350 lb (Retrospec states it includes the bike) |
| GoTrax F3 | 58.3 lb | 672 Wh | Yes | Class 1/2/3 selectable | 264 lb (basis not defined) |
| SASIKEIBIKE 20-inch folder | Not published | 1,040 Wh | Yes - lockable compartment | Not published | Not published |
| Heybike Mars 3.0 | Not published | 624 Wh | Yes | Not published | 440 lb |
Note the two bottom rows. The SASIKEIBIKE folder carries a 1,040 Wh pack — the biggest capacity on this site and, on paper, the obvious boondocking bike. SASIKEIBIKE publishes no weight, and a 20 × 4 fat-tire folder with a 52 V 20 Ah battery is not going to be light. If your rack has a stated limit you cannot responsibly put a bike of unknown weight on it, and that is the only reason the biggest battery here is not the top pick. The same logic rules out the Heybike Mars 3.0 for rack duty, even though it publishes the highest load limit of the group.
Match the bike to the rack, not the other way round
Work out your carrying method before you shop, because it sets your weight budget.
- RV bumper or ladder rack.The tightest budget of all. These are typically rated near 50 lb per bike and they sit at the end of a long lever on a vehicle that bounces. Read your own rack’s label; if it says 50 lb, the Jasion EB5 at 49.6 lb is the only bike on this page that fits, and you should still take the battery off and carry it inside.
- Hitch-mounted platform carrier. The right answer for an e-bike, and what our e-bike car rack pickscover — the hitch racks built for this duty publish per-bike ratings around 60–80 lb and have ramps, because lifting a 70 lb bike to shoulder height is how people hurt their backs. With a real hitch rack, every pick on this page is in budget.
- Inside the truck bed or the toy hauler. No weight limit worth worrying about, so shop on capacity instead, and buy a cover so road grit and rain do not sit on the bike for a week.
- In the back of the rig.A folder is the only sane option, and the isinwheel U3 on 16-inch wheels is the smallest thing here when folded. The trade is a 281 Wh battery, which is a short-range bike whatever the listing claims.
Whatever you choose, take the battery off for the drive. It is the single most expensive component, it is the part that least wants to be rained on at 65 mph, and every bike on this page has a removable pack. Our guide to transporting an e-bike covers the rest, including the rule that stops e-bike batteries flying.
Charging away from a hookup
Here is the arithmetic that makes a trip plannable. A charge costs the battery’s capacity in watt-hours, plus roughly 10–15% charger losses. The 360 Wh pack on the EB5 is about 0.41 kWh at the wall; the 672 Wh pack on the F3 is about 0.77 kWh. At the US average residential electricity price both are small change — we show the full sum in our charging-cost guide.
Off-grid, the figure you care about is not cost but draw. A typical value-bike charger is 2–3 amps at 48 volts, so call it 100–150 watts of continuous load for several hours. That is an easy load for a 2,000 W inverter generator and a serious one for a modest solar setup: a full 672 Wh charge is most of a day’s harvest from a 200 W panel. Plan on charging while the generator is already running for something else, and do not expect to top up a big fat-tire pack from solar alone.
Two rules that are not negotiable, both straight from the CPSC’s micromobility guidance. Charge where you can see it and where a fire would not trap you — not overnight, not in the sleeping space of a trailer, not blocking the only door. And use the charger that came with the bike. If you need a spare because the original lives at home, buy the one that matches your pack’s voltage and connector from our charger picks, and read are e-bike batteries interchangeable first, because “48 V” on two labels does not mean two packs are the same.
How far will one actually go on a trip?
Use the same planning figure we use everywhere on this site: about 20 watt-hours per milefor a value e-bike with a rider using assist sensibly on rolling ground. That puts the EB5’s 360 Wh at roughly 18 miles, the Chatham the same, the F3’s 672 Wh at roughly 33 miles and the U3’s 281 Wh at roughly 14 miles. Those numbers are deliberately less flattering than the box claims of 40–60 miles, and they are the ones that survive a loaded bike, a headwind and a throttle.
For camping that is usually plenty, because the riding is a loop road, a general store run and a rail trail rather than a commute. If your trips are longer than a tank, the honest fix is a second battery rather than a bigger bike — see how to increase e-bike range for the four things that actually work, in cost order.
What we would skip for this job
Any bike that does not publish a weight. On a rack with a stated limit it is not a candidate, however good the spec sheet looks elsewhere.
A fixed 28 mph Class 3 bike bought for trail use. Class 3 is the class most often excluded from shared-use paths, which is exactly where campground riding happens. The F3 earns its place here because its class is selectable; a fixed Class 3 bike does not.
Fat tires chosen for looks.They are heavier, they cost watt-hours per mile, and on a campground road they buy you nothing. They are worth it on soft ground and gravel — that is the fat-tire page, not this one.
