Customer 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!

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.

Gray Hair Lady and a Juggernaut

More fun than I have had in a very long time. I am not a very adventurous person but a good friend convinced me to get one. LOVE IT. Every time I venture out I get braver. Highly recommend.

Best Ebike!!

I love my Juggernaut Ultra Duo 3! We have gone on many adventures through lots of different terrain. It’s great on gravel, grass, uneven dirt trails and anything I’ve tried it on. With my extra battery I’m not afraid to take long trips!

Laura Robinson
Love this bike!!!

I absolutely love this bike! I’m back on the trails after being crippled for 7 years. I feel like my old self! The staff is very helpful too! The coral pink is beautiful. I can’t say enough good things about biktrix!
