Ask a Question
  • What is the folding size dimension?

    The folding size is 39 inches (length) x 28 inches (height).

  • How high can the seat be adjusted? I am 6' - 1" & wonder if this might be too "low" for me to be comfortable to ride?

    The seat height from the ground (lowest to highest) is 840-990 mm / 33-39 in and the recommended rider's height is 4’75”--5’83.

  • How long will the free holiday shipping deal be going on? Does this deal happen regularly?

    Hello -  We offer Free Shipping because the shipping is well over $100 for many of our bikes and we want to give the best value to our buyers. We like to remain competitive during peak season and offer Free Shipping, but it is not always available. 

  • I'd like to order this bike to arrive after January 14th, but I still want the free shipping deal. Is there any way to delay shipping this to me until later if I order it soon?

    Yes, if you want to get the free shipping holiday deal you can order and then leave a note at checkout with your desired delivery date, or call or email us. Thanks! 

  • Is it waterproof/ok to ride in the rain?

    Yes, it is okay to ride in the rain. In fact, we have received feedback for this EBike that it has performed well without any negative issues even though it got totally drenched.

  • If the battery dies can you still pedal and ride like a normal bike?

    Absolutely. This is a multi-speed bike that has the option for electric accompaniment at any and all desires (automatically or manually).

  • Do you have to put this bike together?


    Thank you for your question. The majority of our  electric bikes come 80-90% assembled. If you do not want any assembly, we are happy to contact your local bike shop for you and deliver it there for assembly. They do charge their own separate fee for their service. Many of our riders find assembly fairly easy, but it is entirely your choice. Please let us know how we can assist you further in finding the perfect EBike for you. 

    Happy Holidays! 
    Relax and Ride
