Revised Design of the XTND Board
You might have noticed we’ve been revising the board’s design, as we mentioned in Update #20. The design has gone through several changes since then, which has been necessary primarily due to changes of internal components. Let’s take a look at the details.
As we mentioned, one of the main reasons for the changes is the battery technology. It made a slight difference in the thickness of the board, which is a small price to pay for better and safer batteries. Moreover, the thickness is different only in the center of the board and not on the sides, which makes it nearly unnoticeable. The new battery pack also has better lifespan and increases output of the motors. And, naturally, it is easily swappable.
We’ve also considered a shorter version of the board, but we agreed it would divert too much from the product you chose to back, though quite a few of you liked it better and riding it in real life was awesome. Nevertheless, the main advantage of a shorter board is that it is more comfortable and easier to carry, but we’re pleased to say we managed this even with the original design and without a significant change in its length. A person of an average height now won’t have to drag the board on the ground when holding it by the trucks. The length of the board is 862 mm (as opposed to the original 900 mm) and the width is 237 mm at its widest point.
Moreover, we readjusted trucks to accommodate weight sensors in order to improve the quality of collecting and processing data, and several parts around the rear trucks were made a bit wider for the sake of durability. We also changed the attachment of the bumpers to make sure they won’t get damaged or detached from the board even with rougher handling.
Since our aim is to make the XTND Board as easy to maintain as possible, the two wheels with motors are now completely covered, which keeps them from getting wet and prevents the dirt from getting in, thus prolonging their lifespan. In order to match all the wheels, we adjusted the front wheels as well so now they have twice as much polyurethane, which will make riding significantly more comfortable.
Now, more testing is ahead of us. We’re putting every bit of the board through all kinds of load tests, with a primary focus on motors, to make sure everything is functional and safe. In the upcoming weeks, we will also work on stabilizing BOM (Bill of Materials) and preparing CAD documentation for the suppliers. This is an essential step for the factory pre-check DFM (Design for Manufacturing) review. It will help us specify cost estimates and manufacturing plans so that we can progress quickly, eliminate risks and save money in case we make changes after the production starts.
That’s all for the design today. How do you like the look of it? We really appreciate all the feedback on the previous design suggestion and we’d be more than happy if you could tell us what you think even this time.
Thank you for your amazing support, we really appreciate it.
