Steven Schmidt
New hub duo

Short version,a10 + . Long version battery cover was off on arrival and fell off on my first ride. It is now taped in place and needs a permanent fix. Thumb throttle is an on/off switch. Can I just unplug. I twist throttle would be better. To summarize, riding is a blast. Steve

Life changing in a wonderful way

These bikes are amazing! I’ve been active much of life, with a wall full of event medals to show for it. About four years ago I suffered a hip injury that really slowed me down, I put on weight, got depressed and thought my adventure days were behind me. Then I got this bike and in just six days I’ve already gone 200 miles and explored areas I thought were beyond my reach. It’s opened up so many possibilities and I’m already planning longer rides and trips with the bike.

It is built very sturdy, I’ve taken it up some very steep loose gravel hills and some barely-there trails through the woods and it’s handled everything I’ve thrown at it. This past weekend I did a range test, I rode 70-miles on PAS 1 and returned home with 55% battery left on a dual 17.5ah (35ah total) setup.

This bike is everything I hoped it would be and more. It’s so liberating knowing that hills and distance aren’t really an issue anymore, and if I want to arrive somewhere fresh I just use PAS 5 so I don’t break a sweat. The bike will allow you to work as much or as little as you want. If you want a workout it can do that, if you want little to no effort transportation it can do that too.

If you used to be active, or want to be active but life and injuries have slowed you down and prevented you from getting out, this could be the ticket to getting back to what you love doing.

Do pay attention to the sizing guides. These bikes are bigger and heavier than your old 10-speed. When in doubt or on the line between two sizes you will probably be better off with the smaller one.

I went with a dual battery setup because I heard people talk about how these bikes encourage you to get out more often and stay out longer. They weren’t wrong, that’s exactly what I’ve been doing and very glad I got the second battery. The Pannier bags were a great add on as well for packing snacks, drinks, rain coat, and emergency tool kit for longer rides.

Overall I’m very happy with the fit and finish and the performance of the bike, all of my expectations have been exceeded. Customer support has been very responsive to questions I’ve had. I would Highly recommend Biktrix, great company building an exceptional product and they genuinely care about delivering an amazing experience for you.

Wife's bike

She is very happy with the Juggernaut Hub Duo Step-Thru. I was able to get it setup perfectly for her as she is only 5ft2in tall. The bike has great power and battery life. She's a happy customer!

Neil Gongaware

We bought both a step through and a step over and are happy with both. Performance is good, quality seems good so far. Very simple set up, no issues.
I also got the suspension seat, still working out a tilting issue, I’m afraid to over tighten the bolt for the tilt. The suspension seat is very comfortable, changing the block to your weight is important.
Make sure you check all fasteners, even the factory one.
Thanks Neil
