With a maximum gross vehicle weight (MGVW) of 190 kg (419 lb), it’s built to handle everyday errands and more. As our range of accessories continues to expand, you’ll have plenty of ways to carry what you need.

1. What is a bike’s Max Gross Vehicle Weight?
The MGVW is the maximum weight that a bike has been designed to safely carry.
This means the weight of the Bicycle1 + Accessories + Rider(s)2 + Cargo + Trailer3 must be less than the MGVW for safe riding.
- Bicycle = Refers to the weight of the bike plus battery.
- Rider(s) = Refers to the weight of the cyclist and any passengers.
- Trailer = Refers to the weight of the trailer with no braking system AND the weight of any cargo or passenger(s) on the trailer. Trailers with a braking system should NOT be included in the MGVW calculation.
2. How much cargo can the HSD Gen 3 carry?
2.1 Maximum rear rack weight
The HSD Gen 3’s Atlas H rear rack has a maximum weight capacity of 80 kg (176 lb). While the rack is built tough, always make sure the combined weight of your passenger, rear cargo, and rear accessories stays within this limit.
2.2 Maximum front cargo weight
The Combo Mount is a robust cargo mounting point on the head tube of the HSD. You can attach a front rack with a maximum load of 20 kg (44.1 lb), such as the Transporteur Rack or Hauler Rack. It’s also possible to install the KLICKfix® compatible Luggage Truss CMT, to which you can attach bags, baskets, and racks.
2.3 Maximum accessory weight
Each accessory you add to your bike has its own maximum weight capacity, which may be lower than the HSD’s rear rack or Combo Mount limit. Please make sure to follow the individual accessory’s guidelines.
2.4 How to calculate the HSD’s total cargo weight
To determine the maximum cargo weight you can carry on the HSD, use the formula below. The HSD Gen 3 has an MGVW of 190 kg (419 lb). From that, subtract:
- the weight of the bike itself;
- any installed accessories;
- the weight of the rider;
- and the passenger on the HSD.
If you are towing a trailer, don't forget to also subtract:
- the weight of the trailer;
- and any cargo or passenger on the trailer.
Please note that trailers with independent braking systems should not be included in the MGVW calculation.
2.5 Guideline for comfortable riding
To maintain a stable and confident riding experience on the HSD, most riders find they can comfortably handle combined passenger and cargo loads up to approximately 80% of their own body weight.

2.6 Should I carry cargo on the front or rear of the HSD?
Why not both? The HSD is made to carry plenty of stuff both on the front and the rear. While you can use both ends of the bike for cargo, the rear rack can handle substantially more weight than a front rack. So, in general, it’s best to load your heaviest cargo on the rear of the bike and put lighter cargo in front.
3. How do I load cargo on the HSD?
- A low center of gravity is key to safe and easy handling. Place heavier items on the bottom of racks, panniers, baskets, and boxes.
- Ensure the cargo is balanced evenly on your bike. Avoid putting all of your heavy items on one side of the bike.
- Ensure that items are firmly secured to the bike. Use the Batten Straps to tie down bulky or loose items and prevent them from falling off the bike or moving around during transport.
- Each accessory has its own maximum capacity that is separate from the bike’s carrying capacity. Pay attention to this when loading cargo.
4. Can I use trailers on the HSD Gen 3?
Yes, you can! Using a trailer is your best option when you want to haul something that won’t fit on the bike. Every HSD has a dedicated trailer hitch mount built right into the frame.
