Unit Weight & Transportation

Without the batteries, the Merits Silverado Extreme weighs 253 pounds as a unit; with the batteries installed, the weight increases to 387 pounds. The scooter’s weight has a great effect on how portable it is and easy to transport. The Merits Silverado Extreme may be difficult to carry and store due to its hefty weight. Users who frequently travel with their scooter may need additional help or equipment to lift and transport it, which makes it less convenient for them.

Similar to this, the Afiscooter S4 weighs 342 pounds overall, with a base weight of 238 pounds and an additional 52 pounds per battery. The Merits Silverado Extreme is heavier than the Afiscooter S4 and also significantly bigger. This makes it slightly more difficult to transport and store, however at these weights, transporting the scooter will invariably require a platform lift, carrier or trailer, with those extra pounds not making a significant difference.

One circumstance where that small difference can make a difference is if your car has limited tongue weight and the weight of a scooter and lift together is close to your maximum allowance. In this case, every pound can make a difference and a difference of 45 lbs can mark the difference between staying within your recommended limit or exceeding it. For instance, if your lift weighs 150 lbs, and your S4 scooter weighs 342 pounds, this results in a total of 492 lbs. This is under 500 lbs which is a common tailgate hitch limit. On the other hand, at 387 lbs, the Silverado would exceed 500 lbs making it harder to transport.

Mobility scooter dimensions are quite important since they affect how easily the scooter can be carried and moved around in confined locations. The Merits Silverado Extreme is 61″ in length and 29″ in width overall. While the scooter’s dimensions provide the user plenty of room, they also make it rather bulky and possibly challenging to carry or store. Unlike a folding mobility scooter, the Silverado is a big scooter with  82.7″ turning radius which may make it difficult to maneuver in confined places.

On the other hand, the Afiscooter S4‘s overall width is narrower at 27 inches as opposed to the Silverado’s overall width of 29 inches. The Silverado, however, has a length of 61 inches as opposed to the S4’s 65 inches, making it slightly shorter overall. This facilitates movement in narrow spaces such as entrances. The Afiscooter S4 is a slightly better choice for customers who need to move or store their mobility scooter due to these dimensions.

In conclusion, the Afiscooter S4 has a somewhat smaller footprint and weight than its competitors, making it easier to move and maneuver in confined situations. It also makes it easier to transport if using a hitch lift or carrier.
