A 150kg maximum system weight does not mean an eMTB can carry a 150kg rider. If the limit includes the whole system, the bike and everything carried on it use part of that allowance. There may also be a separate rider limit that is lower still.
The number to check is the one for your exact bike, model year and equipment—not a figure copied from another model in the same range. This guide explains the arithmetic; it does not replace the manufacturer’s limits.
What does system weight include?
Start with the complete ready-to-ride bike, the rider and their equipment, plus carried luggage. Include the fitted battery, pedals, bottles, tools and bags. Do not count an item twice: equipment already included in the bike’s measured weight does not need adding again.
Manufacturers define their categories in the manual or load table. For example, Electra’s owner’s manual defines its weight limit as rider, bicycle and gear/cargo. That illustrates the distinction; its model-specific limits are not ratings for your eMTB.
A simple 150kg example
Imagine a bike with a stated 150kg total-system limit. The complete bike weighs 25kg, and clothing, helmet, shoes, water, tools and luggage together weigh 5kg. The arithmetic is 150 − 25 − 5 = 120kg remaining for the rider’s body weight.
Those are hypothetical figures, not a recommendation for a particular bike. If its separate rider limit were 110kg, the 120kg result would not override it. If the manufacturer includes equipment within “rider weight”, compare the rider and that equipment against the rider limit too.
Why two limits can apply at once
The Grand Canyon:ON AL 7 product page gives a useful real example. It specifies a maximum total of 180kg, but separately limits the rider—including luggage, clothing and seat packs—to 110kg. It also gives a 50kg maximum for a trailer and its load. The bike, accessories and any additional loads remain part of the total.
You cannot add every individual maximum together and assume the result is allowed. Both the overall limit and each applicable individual limit must be respected. Nor does a trailer allowance mean the same weight can be transferred to a backpack.
A five-minute check before buying
1. Identify the bike. Record the exact model, year, frame size and any changed components. Ask the manufacturer or supplying dealer for the relevant load table if it is not clear.
2. Read the definitions. Look for total/system weight, rider weight and any separate luggage or accessory limits. Cube’s support guidance directs owners to the approved limits for their particular model and model year, alongside its intended-use classification.
3. Weigh the actual setup. Use the bike as you ride it, not a headline weight that excludes pedals. Weigh yourself with riding equipment, and account for water and tools without double-counting them.
4. Check every applicable limit. A higher-rated replacement wheel does not, by itself, provide approval to exceed the complete bike’s limit. Ask for confirmation where component and bike documentation differ.
5. Keep the result with the bike’s documents. Recheck it when adding a larger battery, luggage or accessories. If a figure is missing or ambiguous, resolve it before riding with that load.
Weight capacity is not a terrain rating
Being within the weight limit does not make a bike suitable for every jump, drop or bike park. Intended use is a separate check. Likewise, increasing tyre pressure or suspension pressure does not grant a higher approved load limit.
Once you have established a suitable bike and load, use the manufacturer’s setup instructions and our eMTB tyre-pressure guide to work on ride setup. When comparing full-power eMTBs, put the load limits beside price, size and battery capacity—not at the bottom of the shopping checklist.
