Customer Reviews

Based on 75 reviews

After what I would call an unhappy wait for the delivery, we got our bikes
Hub Duo for her
Ultra Duo 3 for me
We must say we are very pleased with the bikes, the service the day we picked them up and the apology for the long wait.
Ryan at the Saskatoon store was exceptionally good as a man to deal with

Long wait

We bought two bikes. Hub duo and the Ultra dual 3
We were told it would be a few
Days to get them in, only because of the colour choice one one of the bikes.
It’s been three weeks and the excuse is we have 200 bikes come in to get ready, this is our busy season. If you bought in December we could have it sooner

I asked if they could try to have it ready for Saturday when we are in town, the answer. NO. We are closed this Saturday for the long weekend.

Well………. I have owned a couple or three businesses, when it was our “busy season” we worked overtime and 7 days a week to catch up and ensure we had happy customers
Has anyone any work ethics anymore ?????
Very unhappy customer!!!

Awesome ebike

The Ultra 1000 is a real cruiser…takes the hills with no sweat and the 24x4 inch fat tires are very comfortable reducing many bumps. I also have the extender which still allows room to step thru. I have the smallest extender. The mid drive with torque-cadence is a perfect match. If one can afford the Ultra 1000 go for it, however I think the hub 750 would also be a great second choice. Delivery was only one week. Biktrix support were very helpful on sale and customer tech support have answered all my questions after purchase. Glad I choose Biktrix.thank-you!

Very Disappointed

I ordered the Juggernaut Ultra Duo 3 and was notified that delivery would not be until late April 2023. So I joined a Facebook group. Wow. There are many disappointed Biktrix bike owners in Facebook. I found out there customer service was not very good. So I decided to cancel my order since it was not due until late April. By the way this is only three days after I ordered it. Customer service informed me that they were going to charge me a 10% cancellation fee, even though it was only three days after I ordered it and they were not planning on delivering it until late April. So add me to the long list of disappointed people. You can't call me an owner because I cancelled so as to avoid the headaches that so many other owners had. I encourage anyone interested in these bikes to join that group. Biktrix employees are not allowed to be members of the group

I love this bike. The only complaint I have is the kickstand is too low in up position. I do a lot of off road trails and it hits rocks etc. I put an after market one on.
