**Please note that information regarding the expected range on a single stock battery charge on one of our e-bikes is an estimate, not a guarantee. There are many factors that contribute to the actual, real-world range for an e-bike battery such as the age of the battery, temperature, level of assist, speed, payload, and terrain. Depending on these various conditions, it is possible to get less than the expected minimum range or greater than the expected maximum range.

NO OWNERS MANUAL

ONE BATTERY CAME DOA AND YOU WOULD THINK SOMETHING YOU PAID 3700 FOR WOULD COME WITH A OWNERS MANUAL. I WAS HOPING FOR A SMOTH SET-UP BUT WITH NO PRINTED MANUAL IT IS A JOKE. THE ONLINE INSTRUCTIONS SUCK AND EXPLAIN ABSOLUTELY NOTHING IN DETAIL. I HAVE BOUGHT OTHER EBIKES AND THE MANUAL FOR THE BATTERY AND CHARGER WAS OVER 100 PAGES AND ANOTHER 50 FOR THE MOTOR.

Juggernaut classic duo step-over

I have not been able to test the bike because there is an error in the e-bike panel. I have been unable to speak to a representative from the company to assist me in resolving the problem. The e-bike did not include a manual and it was not practical to follow instructions on-line. In addition, I purchased additional lights and installing the additional bike parts has been challenging. It would have been a lot easier to get the bike all ready assembled, tested, and validated. At the moment, I need technical support to get back to me so that I complete the e-bike assembly and can be able to ride the bike and provide a better feedback on the bike performance.

Great bike

Loving the juggernaut classic duo. Got the bike a couple of weeks ago and have been putting some miles in it. Rides great, climbs hills easily, and battery life is good so far. Also, I can’t say enough about the customer support. Had a few minor issues after a few days of riding, kickstand lost a piece and the battery lock came loose. Reached out to biktrix and literally had replacement parts 2 days later. I would buy from these guys again in a heartbeat.

Great packaging but

I finslly got my bike after 15 days(because of Purolator)
The packaging was good but it arrived with 2 spot of chipped paint parallel on the front fork. I know it wasnt when i unpacked it because it was on my wood floor on a carpet and it couldnt have been during shipping because the box was intact. That only leaves the factory/warehouse as a possibility. The fenders are high quality, screen's nice, i havent had much change to ride because of the ice and the fact that i dont have studded tyres for this bike yet but everything seems good on that part. I'm probavly going to upgrade the front light.

Love it , great bike . Haven’t had to many rides due to weather . Thanks again , Gary

Juggernaut Classic Duo Step-Over | 52V

Great bike for street

Pro step thru and mid motor it’s fun,but for the beach I’ll use old fat tire for stability as sway front to rear noticeable .the 24 inch tweener size is perfect to mount and position and bike is a lot of fun on flat surfaces
