I purchased a 2017 BULLS ESTREAM EVO 45 I have had a couple of issues arise. Every step of the way they have helped me out and advised me. My bike last week would not turn on. I brought it to Sleek eBikes, Tarrytown, NY. The owner Edward Busk treated me very fairly and ended up fixing it. It ended being a not very solid plug connection in the motor area. Problem solved. The whole affair was very professionally handled and both dealers communicated with each other. (Even Barney at BULLS in California got involved) Very pleased with the outcome with both dealers. If your a Brose aficionado, BULLS seems to have your back when a problem arises.
