Green marks the better published figure. "Not listed" means the manufacturer doesn't publish it.
| Spec | Heybike Alpha | Aventon Ramblas ADV | Weight |
|---|---|---|---|
| Rated motor powerThe motor's nominal (rated, sustained) output as the maker states it, not the higher peak figure. Peak figures appear in each bike's notes. A bike whose maker publishes only a peak figure scores as the lowest rated figure in the category. | 500 W | 250 W | 15% |
| Battery capacityBattery capacity in watt-hours. Where the maker lists only volts and amp-hours, we multiply them (for example 48 V x 15 Ah = 720 Wh) and say so in the product's notes. Larger batteries generally go farther under the same conditions. | 680 Wh | 708 Wh | 20% |
| Claimed rangeThe maker's own maximum range claim, usually in the lowest assist level. Real range depends on rider weight, hills, wind, temperature and assist level, so treat it as a comparison figure, not a promise. Where a maker gives a span, we use the top of it. | 60 mi | 90 mi | 15% |
| Top assisted speedThe highest assisted speed the maker lists, including settings unlocked in the app or display. 28 mph is the Class 3 ceiling, so anything above it scores the same as 28 mph. | 28 mph | Not listed | 10% |
| Payload capacityThe maker's maximum load for rider plus cargo. Where the maker gives a gross vehicle weight instead, we subtract the bike's weight and say so in the notes. | 400 lb | 300 lb | 15% |
| Bike weightLighter bikes are easier to lift, carry upstairs and ride with the motor off. A weight published without the battery is not comparable, so it shows as Not listed. | 71.6 lb | 54 lb | 10% |
| Motor torquePeak torque in newton-metres as the maker states it. More torque helps on hills and when starting with a load. | 105 Nm | 100 Nm | 10% |
| Hydraulic disc brakesYes when the maker lists hydraulic disc brakes. They generally need less hand force than mechanical (cable) discs. | Yes | Yes | 3% |
| Water resistanceThe water digit of the IP rating the maker lists for the bike (the second digit, so IPX5 and IP65 both count as 5). Where only the battery or motor carries a rating, we say so in the notes and leave the bike rating blank. | Not listed | IPX6 class (powerful jets) | 2% |
| Motor | 500 W mid-drive (1000 W peak), 105 Nm | 250 W sustained (750 W peak) mid-drive, 100 Nm | info |
