Customer video review of 70/100-19 E-Moto Motorcycle Inner Tube (2.75/3.00-19) for Surron, E-Ride PRO & Talaria

The tube popped on first inflation; not sure if it arrived with integrity issue or is operational error. Would like a replacement tube shipped.

Store owner replied: Hey Luke, sorry to hear that. Tubes are shipped brand new, and unless there was visible shipping damage, what you're describing sounds a lot like a pinch flat during installation. We've all done it. Motorcycle tubes can get pinched between the tire and rim during mounting, and sometimes they don't show themselves until inflation. For the next install, we recommend using a little baby powder or soapy water and taking extra care with the tire spoons. That goes a long way toward preventing pinches.

Customer photo review of MAXIMA MTL-R Fluid Light Racing 80w Liter

I ordered 2 different items. The first item which was oil delivered within 2 days. Very fast. I was pleased with this. I was hoping the handlebars I ordered would also arrive. Live the Gnar said it was shipping seperate. As of now its been 7days since I placed the order. I reached out via email. Someone responded saying they would look at order and tracking. Its been 2 days and no one has responded. I bought the handlebars as a gift for someone. Definitely would've thought I would've received them or at least received a response from Live the Gnar. This sucks. Either way, I'll just order from another vendor from now on.

MAXIMA MTL-R Fluid Light Racing 80w Liter

Store owner replied: Hey Tony, glad the oil got there quick. The handlebars shipped separately, which is pretty common when different products come from different warehouses. Oil also has to be packaged separately for shipping reasons. The tracking for the bars was emailed directly to you, and they were already on the way when this review was posted. We totally understand being excited for a gift to arrive, but a one-star review feels a little harsh for an order that was shipped and in transit. Either way, we appreciate the business and hope the bars worked out once they landed.

Customer photo review of Fly Tour Roller Bag Black

I race BMX in Northern California. I needed a gear bag for helmet, pads and Knee Braces. This Fly bag is perfect. I will be ordering another. My wife wants one for when we travel to State and National races.
