Bolt-On Fin Box Adapter (K-1 & J-2 Motors)

I purchased a Jupiter Defiant Battery from The Prime Pinnacle on May 18, 2026, and overall I could not be more impressed with the customer service and support I received throughout the entire process.

The ordering process was smooth and easy, and within the next business day I had my FedEx tracking information. Unfortunately, much to my dismay, I received the wrong battery — but after reviewing my order history, I realized the mistake was completely mine. I had accidentally ordered the Jupiter Defiant “Pro” Battery instead of the standard Jupiter Defiant Battery. Doh!

I immediately reached out to The Prime Pinnacle and explained my mistake. I had the pleasure of speaking with Nick from customer service, who was absolutely wonderful. He quickly generated an RMA so I could return the incorrect battery without any hassle. As soon as the returned battery was received, the collaboration between Jupiter Bike and The Prime Pinnacle ensured that the correct Jupiter Defiant Battery was sent out promptly. Nick continued to follow up with me throughout the entire process, which I truly appreciated.

Once I received the replacement battery, I charged it overnight for approximately 10 hours. I was excited to finally get back out for a ride, but then disappointment set in. After installing the battery, I only had 1 out of 5 bars showing on the Battery Power Meter. I immediately thought I may have received a defective battery.

I contacted The Prime Pinnacle again, and Nick called me back almost immediately. It turns out that because my Jupiter Defiant Bike is a 2023 model, the newer battery requires an upgraded battery plate. Since I already had a battery plate installed, I initially didn’t realize I needed to replace it with the updated version. Nick coordinated a call with a Jupiter Bike technician, who clearly explained the reasoning and walked me through the installation process.

As soon as I installed the upgraded battery plate — voila — everything worked perfectly!

I followed up with Nick afterward to personally commend him on his outstanding customer service, professionalism, and genuine commitment to resolving my issue. It’s rare these days to find someone who follows through so thoroughly and truly cares about the customer experience.

I would highly recommend The Prime Pinnacle for your e-Bike needs and would absolutely do business with them again.

Handles inclines without issue and still has plenty of power left. Screen is clear even in bright light. Quality seems premium. Folds compact enough to store in my condo. Love it

I use this on remote job sites for power tools, compressors, and lighting. The 7200W output handles everything I throw at it. Runs all day with solar panels connected. The LiFePO4 battery feels rock solid and the app features are actually useful. Best power station I’ve owned.

As someone who grew up playing in Japan, I’ve always respected Honma. These clubs exceeded my expectations. The shafts feel perfectly tuned and the forgiveness on mishits is impressive for such a workable set. Beautiful craftsmanship that shows in every detail. These are now my forever clubs.

This scooter handles my hilly commute in Seattle like a champ. The suspension is smooth over cracked roads and the range easily covers my 22-mile round trip even with some elevation. Love the bright TFT display and turn signals — makes me feel way more visible in rainy weather. Folds easily for my apartment too. Highly recommend.

I bought this for my off-grid cabin in the mountains of North Carolina. It powers my well pump, tools, and entire cabin setup smoothly. The expandability gives me peace of mind for the future. Battery heating works great during cold winter nights. Very impressed with the build quality.

After 30 years playing every premium brand, the HONMA BERES 10 5-Star is on another level. The Japanese craftsmanship is flawless - you can feel the quality immediately. I gained 12 yards on my driver without changing my swing, and my ball striking across the set is noticeably more consistent. The lightweight construction prevents fatigue even after 36 holes. A scratch golfer friend called the driver the best-feeling club he'd ever swung. The Prime Pinnacle's service was excellent throughout. Expensive? Absolutely. But this is heirloom-quality equipment that performs at the highest level. I'll play these for the rest of my life.

I use this for work and weekend errands. The longer wheelbase gives it a stable, full-size feel while still folding for my SUV. The suspension absorbs bumps on our uneven roads really well. I’m getting solid range and the disc brakes feel safe in traffic. Love how practical it is.

As full-time RVers traveling across the Southwest, the F5000LFP has been a game changer. We run our air conditioner, microwave, and Starlink without issues. The 240V capability handles our bigger loads easily. Solar input is fast and the battery lasts longer than expected. Worth every dollar.

Bought the ST version and I’m getting close to the advertised 34 miles. The wide footboard and suspension make it comfortable even after 45 minute rides. Acceleration is strong and it climbs hills without struggling. The USB port is a lifesaver for keeping my phone charged. Super happy with this purchase.

As a full-time RVer traveling across the Southwest, this bike is perfect. Folds compactly for storage in the RV bay and sets up fast when I want to explore new towns. The 20” wheels and suspension handle light trails and pavement smoothly. Battery lasts long enough for full days of sightseeing.

I’ve played many high-end sets over the years, but the Beres 10 5-Star is on another level. The feel at impact is buttery smooth and the distance is effortless. The gold accents look stunning in the bag. Took it out in Scottsdale last month and shot my best round of the year. Absolute masterpiece.

These Honma Beres clubs are a work of art. The balance and feel are outstanding, especially on the forged irons. I play a lot in the Pacific Northwest and they perform excellently in softer conditions. The 5-star quality is evident from the moment you hold them. Truly special set.

Playing in South Florida, these clubs handle the humid conditions and firm fairways beautifully. Launch is high and consistent, and the irons give me confidence on approach shots. The cart bag is premium quality too. Everything about this set feels first-class. Very happy with my purchase.

Got this for weekend rides around Atlanta and longer errands. The suspension really absorbs bumps well and the seat is surprisingly comfortable for longer rides. I’m consistently getting 28+ miles on the LT battery. Turn signals and lights are bright and useful for city riding. This thing just feels well-built.
