Do not buy .. Here is my review
The Rize Fixie I bought is a dud and the customer service is dishonourable.
First, I received my bike with a defective LCD display. Rize thought it might be a controller issue, and sent me a controller with a video on how to replace it - but Rize would not cover the labour to have it done by a mechanic. There was the option of a complicated procedure, which included removing a part with a warning that removing it would void the battery's warranty. I decided not to even attempt it, so I was riding with a faulty LCD display where the odometer and speedometer did not work at all. I had to use the Strava app on my phone for this purpose. Considering it was a new, never-ridden bike, I would have expected the repair to be covered.
Second, within the first week of riding, the crank arm bolts kept loosening. I had to pull over and tighten them every 15 minutes. A mechanic fixed them with the proper torque and loctite and said it was strange to have to do this repair on a new bike.
The biggest problem: after three months of riding (commuting to work on a good smooth road, and I am a light guy), the back wheel rim broke at the weld. I brought it to a bike mechanic, who told me it was an obvious factory manufacturing defect, and that any reputable company would cover such an obvious defect. Otherwise it would cost around 300 dollars to rebuild the wheel. He also told me it was very dangerous to have been riding such a rim and that I could have been seriously injured.
Unfortunately, I was not dealing with a reputable company. Upon emailing Rize with photo documentation,and calling them, they did not respond for 9 days. After this long wait, I received an email saying they would send a rim but would not cover the cost to rebuild the wheel. A rim costs $50-100, but the rebuilding costs around $300. This is totally unacceptable.
On top of this the battery does not last anywhere near their stated mileage, unless maybe on their lowest setting. I was getting around 35 km while mostly on the fourth setting.
Rize customer service obviously lacks any integrity. And this is the product I most regret buying in my entire life. Literally. read more
