Perfect Ebike for Suburbia

This is a big bike with tons of capability. I bought the additional 884Wh battery which gives the bike an almost unbelievable amount of range if you pedal as much as you can. It also adds a bit more weight which can be used as increased resistance for more exercise. This bike can be ridden reasonably well under leg power alone and it does provide a good workout. Build quality is mostly very good. I don't really enjoy the cadence control as it feels like the bike is doing too much of the work even on the low settings so I set it to 0 and only use the throttle for assistance when I need it. I also found the shifting imperfect even with the electronic interruption when changing gears. But it's nothing you wouldn't expect from a derailleur style transmission. Some skipping can occur when changing gears so to reduce the likelihood of chain damage, I tend to change gears with pedal power only and once I feel comfortable that the bike is in gear perfectly, I will add motor power. While some shifting is necessary, if you are riding on mostly flat ground and putting in effort pedalling, you could easily leave the bike in the middle gear range, only shifting into 1st for steep hills or better control off-road. I barely go above gear 7 because it seems only beneficial for gaining lots of speed down a long hill. Those high gears only seem to strain the motor too much otherwise. The regular brakes are absolutely perfect. Lots of stopping power so I have a hard time recommending the more expensive option. I like the fat tires too an run them at 18PSI because I mostly ride on the street. They have been perfect on the snow too. One thing that is a little annoying is that the main battery and second battery can't be charged with a single charger so I have to remove the second battery to charge it. But it isn't big deal, especially because the bike has so much range the way I ride I don't need to charge frequently. It definitely is nice to have tons of range. It makes this bike capable of replacing car usage which is so awesome. This is the kind of EV that is good for the environment, not electric cars. Save your money. Don't buy another car. Buy one of these bad boys instead. You won't regret it!

Love it

It’s better than I thought it would be. Regret not buying an e bike years ago. This is a great ride and will even be better when all the ice is gone!!!

Just assembled today

Hi there, I’m very excited about my new bike. I assembled and took it for a very brisk Canadian winter ride and she works great so far. I am however, disappointed with the delivery aspect. Purolator kept the bike there for at least 5 days stating that the package was too heavy. They did not contact me and were not able to give a delivery date when I contacted them. Ultimately I became frustrated and drove into Kingston to retrieve it myself. A+ bike so far, F for purolator. I know you can’t do anything about that, but I would suggest airing your disappointment in their service.

A good ebike from a good company!

The Juggernault Classic Duo is my first ebike. It is well made and can be customized as my needs change. I have only ridden the bike a few times but my initial impressions are the motor has plenty of power and the ride is smooth and comfortable. I like the fact that Biktrix is a Canadian company and the owner/CEO is actively engaged on Facebook. I am confident that the Juggernault Classic Duo will prove itself to be reliable and durable and, more importantly, if I run into any issues with my Juggernault that Biktrix will work with me towards resolving them.

Update 2.0

It's been 2 months and 500 miles, bike is holding up great. Power is great, I feel 750 watt is plenty. Not crazy powerful, just enough for long rides and off road action. I didn't want a moped. Did beef up the derailleur, but not a big deal, I wanted to make sure I could push this bike hard if needed without damage. Customer service has been excellent with any questions I have had. For an ebike with this set up and components this is the one in this price range. With so many new companies coming out so quickly I'm pretty sure Biktrix is going to be around awhile.
