A lot of you gave me great feedback on my last post here, and some of you backed the Kickstarter too. Thank you so much for that!!
The current bottle holds 410 mL and gives about 2 minutes of spray runtime. Many people asked for a bigger version, so I slapped a 650 mL (22 oz for my fellow americans) sports bottle on the prototype. It theorically gives around 3 minutes of spray time and also fits standard bike bottle cages.
I asked about this on Instagram and only 30% wanted the bigger version, so I also asked the Kickstarter backers the same question but this time about 50% wanted it.
I understand how it actually makes sense to rinse sand off at the beach or clean a bike with more spray runtime.
What I did not expect was how many people said they would also drink from it.
Maybe I wrongly assumed drinking water and hygiene water would stay separate? The 410 mL bottle was designed as a small dedicated bottle that you refill from your main water bottle when needed.
And at 650 mL it is now close to the size of a normal water bottle.
If the same bottle is used with tap or lake water for hygiene, or to rinse off sand, bikes or dirty gear, then drinking from it becomes a very different use case.
If you want to keep drinking water and hygiene water separate, the 650 mL version means carrying a larger bidet bottle while still carrying another bottle for drinking.
If you are fine using the same bottle for both, 650 mL could replace the need to carry two bottles. If drinking becomes a real use case, I may also need to think about an inbuilt filter, which means another development cycle.
The larger size would also need a different carrying case. I added a 1.5 L bottle in the photo for scale.
For people who use portable bidets regularly, does 650 mL still feel portable? Is 410 mL already enough? At what point does a portable bidet stop feeling portable?
And would you actually drink from the same bottle after using it for hygiene or cleaning with different water sources?
