**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.

Love my red rocket!

I am enjoying this bike! Service was great, it was put together for me and ready for pick up. It works well on off road terrain and cruising on the street.

Challenger 2

Not had much opportunity to ride it much yet, the but the build quality is outstanding! Paint finish is awesome & ride is very smooth. I do feel like the rear shocks are way too stiff for a lighter rider, be good to have a lighter weighted rear shock choice in the future. Unlocking just a little more performance from the motor in terms of top speed would be a good thing. That being said I would highly recommend this model!

Broke after 18 months

As much as I appreciate the discount on new parts,(needed or not) they were still expensive and are not returnable (even if they come with the motor cord too short). And it still doesn't work. So buy another part they don't back???

If we have to buy disposable bikes, then we might as well buy them from the country that makes them for half the price. China.
Not impressed at all.

Never too old

This bike arrived within 10 days of ordering.Although being very heavy we managed to get it off the delivery truck and into the lobby and then to the apartment.The boxing was more than adequate and the bike had no marks or scratches.Assembly was straight forward except for having to determine, without instructions,the assembly or the front axle,that does need a bit of mechanical knowhow.All in all,quality construction was evident and I was taken a back by the appearance overall,good value for the money spent and will enjoy this bike at the age of 82 when spring comes around.

Haven’t received

I can’t comment because I have not received the bike

Super challenger in mountain forestry roads of vancouver island

Pros
-Ridiculously powerful with tons of torque. The mountain hills are not a challenge.
- I'm 250 lbs and the top speed is 52km/h
- I go on long trips and come back with barely 1 bar of power missing.
- The bike went on sale a few days after I bought it and the good folks at biktrix gave me store credit. Very appreciated.
- Shipping to a remote fishing village is difficult. The first bike came on a sea plane. However, biktrix went above and beyond to ensure it got here okay.
- Bikes arrived with no damage
-Was easy to put together. Took me about 45mins and I am not a mechanic type person.
-Easily the best purchase I've made in years
Cons
- slightly too short for me. The 3" seat riser has been on backorder and I'm still waiting.
-Seat is a bit hard for long rides. However, I imagine it will soften up a bit and my partner is making some seat cushions. Still prefer the moped seating though.
- Had a difficult time trying to keep the front lights tightened, but think I might have it now.

Overall, super happy with this purchase. Would buy again.
