Spare Battery Not Available

The bike itself is decent but I'm giving a 1 star review because I can't find a spare battery. I've contacted Sport Chek customer service and they do not sell spare batteries for this bike. does not have any contact information, everything points back to the retailer and/or Sport Chek. I contacted Blackdiamond (US) and they do not support this product and recommended I go back to Sport Chek. It should not be this hard to find a spare part for this bike.

Mine is for sale for parts. Hubby got the electronics wet . Won't work anymore. Battery wasn't in...

If you're interested I'm at [****]

Unfortunate experience: very unreliable e-bike

I purchased this bike from Sportcheck online. It was delivered two weeks after placing the order, Ok !
The bike arrived without any tools for assembly, Ok !

I was initially pleased with the bike's appearance and overall finish. During the first week of use, everything seemed to be in order. Unfortunately, in the second week, the chain started skipping frequently, and after just two weeks of use, the bike completely broke down. The incident occurred as I was riding; suddenly, the chain snapped and caused me to lose my balance, resulting in a fall. NOT OK!

I promptly took the bike to the Sportcheck store for servicing. It took them 4 days to rectify the issue. However, I encountered an unsettling response from one of their mechanics. He attempted to attribute the breakdown to my actions, suggesting that my use of the smallest gear only had caused the gear to wear and crack, subsequently breaking the chain. He even advised against using this gear and recommended shifting to other gears to avoid a recurrence. Furthermore, he warned that if the gear were to crack again, they would not provide further repairs. Yet, there are several points that the mechanic seemed to overlook:

Firstly, my bike was only two weeks old and should not have experienced such a rapid breakdown unless a significant underlying issue was present.
Secondly, I frequently shifted gears while riding.
Thirdly, I am a mechanical design engineer with over 15 years of experience in the field. The design of this bike is very weak. Upon my initial observation, I questioned the durability of these small chains and sprockets against the combined forces of human pedaling and motor assistance. The bike's design appears fundamentally flawed, disregarding basic engineering principles of power transmission systems (chains and sprockets).
Lastly, the larger gears (lower speeds) appear impractical, especially in an electric bike with motor assistance. In reality, riders tend to utilize the smallest five gears at most.
I deeply regret my decision to purchase this bike and intend to work with Sportcheck to arrange its return. I strongly advise potential buyers to think twice before buying this bike.

Powerline ebike

It is a pretty good ebike for the price I paid. The fork is crap but the frame, motor and battery seem to be decent quality. With a few upgrades, it will suit my needs.
