My New VoltBike Mariner

I am a big VoltBike Fan,…have just purchased my second VoltBike Mariner. I have also purchased an VoltBike Urban as a gift for my sister and a VoltBike Yukon as a gift for her hubby. I have put many miles on my bike since purchasing my first Mariner in 2018 and have never had any issues whatsoever to deal with. These bikes are reasonably priced, very durable and an absolute joy to ride !!!

My 2 mariners step true

Wow, those bikes are something else. Even my wife who hasn't ran a bike for the last 20 years found it easy to ride after a good training.
They are a bit heavy but for this reason they hold on the roads.

Early reveiw

I have only had this bike for a week less then 10 km, but it seems to be a decent bike. The only thing I don’t like is the seat on it, volt skimped out on it and is not very comfortable, I would have liked a wider seat with a back rest. Other then that it seems to be a solid bike, and feels good.

Enjoying my bike

I received my bike April 16th and I am new to the e-bike universe. I have only been out on a couple of trail rides so far and the bike works great. No issues to date. Looking forward to riding a lot more now that the weather has started to warm up. If I could of rated a 4.5, I would have. I never rate at the highest as everything in life can always improve.

Great bikes

Very happy with our bikes !
One thing you can improve on is your “ next day shipping “. It is obvious that your company is not able to meet that commitment . It would be best that you commit to a more realistic timeframe for shipping your bikes so as to not cause a lack of confidence in your business . Do better with this aspect of your business and I would have given you 5 stars . So far we have been happy with our bikes and the warranty issues ( fine tuning of rubbing brakes ), have been easy to deal with at our local bike shop and reimbursement of fees has been prompt . So we are very impressed with that ! It was a bit concerning how we would be able to utilized our warranty if need be and we were very happy that our concerns were handled promptly and easy to rectify!
