"Today we are reviewing the Surface 604 Boar Explorer and let me just tell you right off the bat here that this is the champion of fat tire e-bikes. Not just because of the quality, and there’s a lot of that to be had here, but because at 4.5 inches wide, this is literally one of the fattest fat tire e-bikes we’ve tested to date.

The Surface 604 Boar Explorer excels at wet, soggy terrain. Swamps, grasslands, streams and brooks. If there’s standing water, the Boar Explorer wants to wade through it, and that’s where these absolutely massive tires really shine." Brent McCluskey — electrified reviews

Fantastic store with amazing staff who really took time with my husband and me. We were able to try out a couple different bikes on an actual road ride and not just in a parking lot. Chris spent a lot of time familiarizing us with the bikes and making sure we were comfortable with them before going out on the road where he rode alongside us giving helpful tips and advice. He was very patient and at no time did we feel pressured to hurry up and "catch on" nor did we feel pressured to purchase a bike. Thank you to all the staff. You really know how to do customer service right.
What to say about BCeBike's customer service? It simply is the best there is on Vancouver Island! I have a two-year-old Velec R48 which I love to ride. Unfortunately, the battery died. I had bought the bike in Duncan, but reaching the business there was painfully unsuccessful. Eventually I contacted Velec in Quebec and they immediately responded and told me to connect with BCeBike in Nanaimo. During a day their store was closed (Monday) I could deliver my bike to have it checked out. Rob the owner phoned me the same day to confirm the battery was dead, but luckily still on warranty. He provided me with a loan battery so I could keep riding and now the warranty is taken care of. On a site note, Rob checked out the bike completely and fixed assembly errors made in Duncan without charging me for it! Rob thank you so much! You are a true passionate business owner, and your customer service is out of this world!! Helma

Friendly staff and so helpful
They all want us to enjoy the experience while riding a bike. tx Cheryl Harvey
We did not even purchase our bikes from bc ebikes and they serviced our bikes and provided us with lots of information to make our biking experience better. Thank you thank you thank you.....I now know why Mitchell from surface 604 was not worried at all about the issues we were having once he knew we took our bikes to your team!

The passion and knowledge that Rob and staff have for the products they sell, as well as the care and expertise they provide in helping their customers keep biking safely. tx Ron
Amazing people ! They are fixing my fathers bike even though it’s a older e-bike and know one else will touch it ! Great service! tx Trevor Sandnes

Stayed after hours to complete sale and complete last minute assembly. Shared operating instructions and safety tips. Very patient with technical challenges of payment process.
