If you pay by credit card, your payment could be somehow denied at the checkout by HJMBIKE system. Because of the higher rate of credit card fraud now, the bank set higher safety payment levels. That's why your payment failed.
HJMBIKE advises you to call your credit card company or bank ahead of time to let them know about the purchase so that it doesn't get declined. Here are three methods to solve the problems:
1. If you have a PayPal account, please try to pay by PayPal.
2. If you do not have a PayPal account, please select PayPal still at the checkout page & click the complete order button.

Then you'll be directed to a page with access to both PayPal and Debit/Credit card payment (for the latter option, you don't have to register for PayPal).

3. Please switch to your other credit/debit cards.

Contact us if you still have any question about the payment.
