This is quite possibly the perfect E bike for someone who can rip, the geometry on this bike is awesome, the power to weight ratio is sick. But also the Bike looks so classic and so clean my wife rides one as well great body position great torque just all around the best bike out there.
After a few months of having the Ultra Flex it is still a solid bike and ride im officially a Zoozer now and I am loving it 💯 💯 💯
Quick response from customer service on compatability.

Everything with ZooZ bikes I’ve been impressed with so far!
The support at Zooz is always great. They are quick to answer questions and you always talk to a human. Drew on their team is especially awesome! Thanks Zooz!
I’ve only put about 69 miles on my bike since I got it a month ago. I love it. I am 47 yrs old 6’ and 215# and this thing still zips. Lots of power. Occasionally I ride with other riders of various speeds. I have no issues at all coming from the rear to the lead bike quickly to control the group. The battery lasts forever without needing a charge, frame and rims are sturdy and nothing seems like it was cheaply made. Its assembly took less than 10 min your of the box. If I had to switch anything it would probably be the grips. I just prefer a different feel but the ones that come standard are fine. Can’t say that I’d change anything else. Great looking and fun to ride! Definitely took me back to HS on my BMX. Except this is much faster!
