How a Motorhome Cycle Rack Affects Your Payload (And How to Calculate It)
At a Glance: Motorhome Payload & Cycle Racks
- Payload Defined: The difference between your motorhome’s Maximum Technically Permissible Laden Mass (MTPLM) and its Mass in Running Order (MRO).
- Hidden Weight: A motorhome cycle rack typically weighs between 10kg and 18kg before you even add the bikes.
- Safety First: Overloading your rear axle can affect steering, braking, and legal compliance.
- E-Bike Alert: Electric bikes are significantly heavier (often 25kg+ each); ensure your rack and rear wall are rated for the combined load.
- Rear Windows: Specific “Short” rack versions, like the Thule Elite G2 Short, are designed to fit beneath or around rear windows.
For many motorhome enthusiasts, the freedom of the open road is only complete when there’s a pair of bicycles strapped to the back, ready for local exploration. However, as installation specialists at Rose Awnings, we often find that the technical side of “payload” is overlooked. Adding a motorhome cycle rack isn’t just about finding space; it’s about safety, legality, and vehicle longevity.
Why does your cycle rack impact payload?
Every motorhome has a legal weight limit, known as the MTPLM (Maximum Technically Permissible Laden Mass). Your “payload” is what’s left after you subtract the vehicle’s empty weight (MRO) from that limit.
When you install a rack, you are consuming a portion of that payload twice: first with the weight of the rack itself, and second with the weight of the bicycles. Because most racks are mounted on the rear wall, this weight is subject to “leverage,” meaning it puts specific pressure on the rear axle. Exceeding this can lead to heavy fines, invalidated insurance, and dangerous handling.
How do you calculate your remaining motorhome payload?
To ensure you stay within legal limits, follow this simple walkthrough:
- Find your Plate: Locate the stage 2 build plate (usually under the bonnet or inside the door frame) to find your MTPLM.
- Establish MRO: Check your manual for the Mass in Running Order, but remember this often excludes “optional extras” like awnings or solar panels.
- The “Real World” Weigh-In: For the most accurate start, take your motorhome to a local weighbridge fully loaded with fuel, water, and passengers.
- Subtract the Hardware: Deduct the weight of your chosen motorhome cycle rack. For example, the Thule Elite G2 weighs roughly 10kg, while the heavy-duty Thule Lift V16 (which features a 12V motor) weighs approximately 18kg.
- Add the Bikes: Finally, add the weight of your cycles. If you have two E-bikes at 25kg each, plus a 15kg rack, you have just used 65kg of your payload.
Which rack is right for your weight requirements?
Choosing between the different types of bike racks for campervans and motorhomes depends heavily on your vehicle’s structural capacity and what you intend to carry.
At Rose Awnings, we offer a range of Thule wall-mounted solutions. The Thule Excellent is a premium choice with a high load capacity of 60kg, making it ideal for heavier loads. If you are looking for convenience, the Thule Lift V16 is a game-changer, as it lowers to the ground via a 12V motor or manual crank, eliminating the need to lift heavy bikes high onto the rear wall.
What is the best bike rack for a motorhome with a rear window?
This is one of our most frequent queries. If your motorhome has a rear window, a standard tall rack may obstruct your view or be impossible to mount safely.
In these instances, we recommend the Thule Elite G2 Short. It is specifically designed to be installed beneath a window or in instances where the distance between the top and bottom fixing points is limited (typically between 50cm and 80cm). Despite its compact size, the Elite G2 Short still maintains a 60kg weight limit, ensuring you don’t have to compromise on strength to accommodate your vehicle’s layout.
Frequently Asked Questions
Can I carry E-bikes on any motorhome rack?
No. E-bikes require racks with higher weight ratings (usually 30kg per rail). The Thule Excellent and Thule Elite G2 series are both e-bike ready, but always check the specific rail capacity before loading.
Does the rack weight include the mounting rails?
Yes, when we provide technical specifications at Rose Awnings, the weight cited includes the frame and the basic mounting hardware.
How do I know if my rear wall is strong enough for a rack?
Most modern motorhomes have reinforced points within the rear panel for rack fitment. If you are unsure, our team can check your vehicle’s specific layout to ensure a safe, watertight installation.
