Some FAQs about Shipping

  1. Do you ship outside Canada? Due to the cost of shipping large products, we do not currently ship outside Canada.
  2. How will my order be delivered? Regular shipping is curb-side delivery. Customers will be responsible for unloading the shipment off the truck. The shipper will call to set up an appointment before delivery. We suggest having someone to help the delivery person unload the shipment.
  3. When will my order arrive? Every product on our site has an estimated Lead Time - the number of business days it takes for an item to be processed and prepared for shipment at the warehouse. To provide you with the greatest selection on the internet, we ship from warehouses all over the country. Each lead time varies based on many different factors. Some warehouses stock items that can be shipped the same day or within 24 hours. Others items require a longer time (e.g. 5 days).

Eunorau | Flash Extra Battery 52V21Ah (2nd) | 52V17Ah (3rd) | Both

Overview

Two reliable lithium-ion battery options designed for the Eunorau Flash: a higher-capacity 52V 21Ah down-tube pack using HYFX-D LG3500 cells and a lighter 52V 17Ah Hailong top-tube pack. Both include a 4A charger and an integrated battery management system (BMS) for safer, balanced charging and riding.

Benefits

  • Extend your ride — higher capacity means fewer stops to recharge and longer range per charge.
  • Less worry about battery health — built-in BMS protects against short circuit, over-charge, over-discharge and over-current.
  • Choose the right balance of weight and range — pick the 21Ah down-tube for maximum distance or the 17Ah top-tube for a lighter bike.
  • Simpler charging — standard 4A charger for routine, predictable recharging times.
  • More dependable rides on hills and longer trips thanks to consistent power delivery and cell balancing.
