I just got a strida 3.2. I was wondering how high I should set my seat? Right now, I have it so I can place both feet flat on the ground when sitting down. Is that too low? Thanks for any advice.
Hi Eric,
I’ve forwarded your case to the customer service of strida.co.uk. Here is the reply: 
it’s a tradeoff between getting your feet on the ground easily, and getting full leg extension, for maximum pedaling efficiency. there is no ‘right’ answer. just experiment until you find the right setting.
make sure to tighten clamp bolts (but not middle bolt without clamp) very tightly.
let us know if you have any other questions, and we’d be happy to respond.
best,
strida customer service
