**Please note that information regarding the expected range on a single charge on one of our e-bikes is an estimate, not a guarantee. There are many factors that contribute to the actual, real-world range for an e-bike battery such as the age of the battery, temperature, level of assist, speed, payload, and terrain. Depending on these various conditions, it is possible to get less than the expected minimum range or greater than the expected maximum range.

did not deliver did not solve the problem

Ordered the bike unlocked it arrived locked my Rad City Step thru has more power. To fix Biketrix mistake I have put my travel on hold while waiting for a cable so I can reprogram the bike. They will not overnight the cable by courier. not sure why when it is Biketrix fault nope gotta go thru the warehouse system and no idea how long that will take.
Typical of a company that is all talk and no action about customer service.This is my 4th bike and will not recommend Biktrix to anyone. Should have repurchased the similar bike from Area 13 bikes in the states. My first one got stolen in New Mexico Thought I would support a Canadian company.. My fault should have stuck with a known company that understands customer service. Horrible so far. Support does not seem to understand their job.
Would not recommend this company. If I could return this I certainly would but i can’t imagine the difficulty doing that.
So now I get to travel the rest of the summer with a 4500 dollar bike that is no better than an Amazon special.
I am almost embarrassed for this company.
Save your marketing dollars I see your ads all over social media. Hire “support" staff that can make things right instead of making excuses!!

Great Bike with Unbelievable Range

Recently bought an Ultra Duo 4 with the extended battery. I've had other ebikes and I've always worried about the range and it affected how I ride. I took this one on a ride over the Golden Gate Bridge up to the Headlands and back for about a 25 mile ride. Not only was I never in remotely worried about the battery level (it was around 88% by the time I was done), but I never wanted for more power while climbing the hills. It was amazing and really fun.

This is a GREAT bike!

A smooth ride and exceptionally easy application of battery assistance. The power levels are fantastic and intuitively selectable. And it looks great too.
