How we picked
We ranked every e-bike in the registry on battery watt-hours first, then removed anything with a pack under 500 Wh, because below that a shift becomes two shifts with a charge between. We then looked for a published load limit, a stated safety certification and a real charging time, and we gave weight to the fittings delivery riders actually use: a throttle, lights and a frame you can rack. We have not ridden every one of these; this is exactly what we do instead.
The arithmetic of a shift
The planning figure this site uses is about 20 Wh per mile for a heavy bike ridden with a lot of throttle, and delivery riding is the definition of that. On that basis the 1,040 Wh SASIKEIBIKE pack is good for roughly 50 miles of stop-start work; the 692 Wh Ranger S and the 672 Wh GoTrax F3 land in the low 30s; and the 528 Wh Jasion Roamer in the mid 20s. Measure your own typical shift in miles before you choose: if it runs to 30 miles or more, the bottom of that list is a one-shift bike and the top is a bike with a margin for the evening rush. Our range guide explains why the maker’s range claim is not the number to plan around.
Cold weather, a heavy bag and hills all push the per-mile figure up, not down. If you deliver in a hilly city, size the pack for the climb and read our hills roundup first.
Why watt-hours beat watts for this job
Every delivery listing on Amazon shouts a peak-wattage number. Ignore it. A 750 W rated motor pulling away from a stop with a loaded bag is what all four picks share, and it is plenty. What separates them is how many times they can do it before the pack is empty, and that is watt-hours. The SASIKEIBIKE’s 52 V 20 Ah pack is the largest published capacity in this registry; its price puts it in the same band as bikes with barely half the battery, which is why it heads this list despite publishing no weight, no class and no top speed. Our motor power guide covers the rated-versus-peak trick in detail.
Load: the number that includes the bag
A delivery setup adds a rear rack, an insulated bag and whatever is in it on top of the rider’s own weight, and the maker’s load limit has to cover all of it. The Jasion Roamer publishes a 330 lb max load; the GoTrax F3 a 264 lb total payload. The Ranger S and the SASIKEIBIKE publish none on the listings we source from, which is a real mark against them for this job and is stated on their cards. Our heavy-rider roundup explains why a load figure without its basis is not comparable across brands.
Charging between shifts, and a second battery
A big pack is slow to fill. The SASIKEIBIKE listing states a 6 to 8 hour full charge, which means a lunch-shift-to-dinner-shift turnaround does not happen on one battery. The practical answer for full-time riders is a second pack, charged while the first is on the bike. The Roamer’s pack is removable and the SASIKEIBIKE lists a lockable battery compartment; confirm on the listing that the pack comes off the frame before you plan around a spare. Read the batteries roundup before you buy a spare: voltage, mount and connector all have to match, and a 48 V pack will not go on a 52 V bike. Charge the spare in the open, on a hard surface, using the maker’s charger; the CPSC’s micromobility guidance is written for exactly this use pattern, and our battery care guide turns it into a routine.
The legality section, in plain words
A large share of the bikes marketed to delivery riders are not legally e-bikes. Anything with a motor over 750 W, or assist past 28 mph, or a throttle past 20 mph, falls outside the three-class system that most states use, and is treated as a moped or motor vehicle that needs registration, a license and insurance. Ride one on a bike lane and you are operating an unregistered motor vehicle with no insurance behind you. Our e-bikes vs e-motos guide explains how to tell them apart from a listing, and classes and laws covers the state rules.
The four bikes here are 750 W rated or less. The Ranger S is a Class 3 bike at 28 mph; the F3 is selectable, so it can be run as Class 2 where a lane requires it; the Roamer and the SASIKEIBIKE publish no class at all, which means you should confirm the shipped speed limit on the display before the first shift and set it to what your city allows. Being able to show that setting is worth more than any spec on the sheet.
Lights, fenders, and a bike that looks like a bike
Delivery happens in the dark and in the rain. The Roamer is the only pick with turn signals and a brake light fitted as standard, which is why it makes the list with the smallest battery here. On the others, budget for a real front light and a rear light from the lights roundup, fenders from the fenders roundup, and the phone mount you will be staring at all shift from the phone mounts roundup. A rear rack rated for the bag is not optional; see racks and panniers.
What we would actually buy
Full-time, flat city: the SASIKEIBIKE, a second pack, and the discipline to set its speed limit to the local rule. Part-time, or a rider who wants a bike that also folds into a small apartment between shifts: the Ranger S. A rider who pedals hard and wants the bike to feel like a bicycle rather than a scooter: the F3, whose torque sensor is unusual at this price. Tightest budget, most nights: the Roamer, for the certification and the signals, accepting that it is a one-shift battery.
