Fantastic bike… one gripe

I love my flat bar Ambition X. Perfect for my mostly paved with some gravel trails I frequent. Stylish and super light! My only complaint is that the handlebars can’t be raised. For us older folks used to higher handlebars this would be a very nice addition to make this bike perfect for anyone who frequents paved/light gravel trails. More options to add on for nighttime riding would be great too. All around happy with this purchase though!

Top Tier Customer Service

I originally visited Poseidon to purchase my first drop bar road bike. I can into an issue with the XXL being out of stock and needing a bike quickly to start my training for Ragbrai in July.

I reached out to Luis over email and he offered to provide service on a flat bar of my size and color to turn it into the drop bar. Their flexibility and willingness to go the extra mile so I could start my biking journey showed me the level of care they have for their customers.
