Customer Ebike of the Month

This ebike was built by Harold. See what he has to say:

“This is my Trek 3500disc. I am running a Calibike set up. 48 volt with a 20 ah battery. I can go approximately 30+ miles without pedaling, at 20 mph, top speed so far 39.8 mph (before the snow got here). This was my first try and currently building number two. This time a Kona full suspension bike. This Trek 3500 is my daily rider and just recently added fenders and studded snow tires. Last week I was riding in about 20 degrees f. and no problems . Today I rode around in 8 inches of snow and powered right through it. I highly recommend Calibike , and Rafe is the best. Great attention to customers needs. …… This is a copy of my ad on Craigslist Kalispell Mt.
I am starting to build ebikes and besides selling some, I am wanting to talk to others in the Flathead, about their attempts and success, and what systems they are using. I am looking for others to ride with, any age or ability is cool. I am currently running a set up that goes 35 miles, @ 18 mph. Hit the number II setting and it goes 28 mph….. III rd speed, 39.8 mph. I can show you how or do it for you. Here is the current bike I ride and I am building another with the same frame only bigger.

I have had some bad luck with foreign batteries

Hi, I bought A 48 V years Ago From you, and that was A very Good Battery, Sence I’ve had Bad Luck with China Batteries, The 48 Volt here has A Charging Port on top, and I have A Custom Case I built on My Basman Strech Cruiser, I wouldn’t be Able to get to the Charging Port, Do you Guys have A Blue Wraped 48v 15 AMP H? If so can you put it up for Sale for me to buy?

By Don

I bought one of your battery’s a little over a year ago love the out put and power , How ever the breakers you put in them are junk ! I had to take out the cheap breaker and I put a 40 amp fuse in place of it just to ride I through the original breaker in the trash where it belongs ..


Hi don
The breaker is from solar industry. I put in because many chinese controllers are unreliable and overload the battery. My thinking was better the fuse than the bms. I do appreciate the feedback. We now have a customer album to showcase customer builds if u get a chance put your build on there. Its at calibike.com

Highest commitment to quality

I use my e-bike for daily transportation (16 mile round trip; 6000 miles to date) and needed a battery with more capacity than my 48v-10ah battery. This battery in the triangular bag works great; fits my bike frame perfectly, and it’s a much better balanced setup than my previous rear rack mounted batteries. Rafe at Calibike provides prompt service; knowledgeable answers and great communication any time I have a question or need assistance. The battery I purchased gives me a 25 mile range (in heavy winds and without using pedal assist mode). Warranty is local (USA) and Rafe works hard to give the best customer service. I am extremely satisfied with this battery and the excellent customer service provided by Rafe.
