The Sonic Stomper has been a long time coming. We set out to design our own eBike. The majority of competing companies rebrand a generic bike, which can be good or bad. We didnt want to be the same as everyone else, and that is when the Sonic Stomper SS was born.
Over the last 2 years we have cut our teeth making eBikes. We have converted our own bikes. We have converted other brands into eBikes. Through it all, we have learned what makes for a good bike, and how many fall short.
One of the main keys is the frame. With a motor, and added speed, the frame becomes the most important design aspect of the bike. When a frame is underbuilt, the sheer torque of an electric motor will cause the frame to twist and contort. If you compare any of our frames to the competition, you will see the frame tubing is significantly oversize, and is not round. Overall, our tubing dimensions are nearly 3 times larger, which increases the strength and torsional rigidity significantly.
Our geometry is a bit different as well. We run a 67.5 head tube angle, similar to a downhill suspension bike. At speed, this helps with stability, and slows down steering inputs to inspire confidence. A twitchy bike can work against you.
Additionally, we worked to integrate the battery into our frame. From a security standpoint, this is better, but aesthetically, it looks so much better. All of the cabling is housed in the frame as well.
The Sonic is truly a purpose built eBike from the ground up!
While most of our competition chooses a rear hub motor, we opted for a mid drive system from Bafang. The smoothness of using a mid drive is unmatched. And just like a car, we feel that it is better to use the existing drivetrain to push power through, rather than a hub. You get significantly more torque, and you can use the various gear ratios to fine tune speed, or your efficiency.
On our SS model, we utilize TRP Zurich eBike specific brakes. We felt it was important that the right brakes went onto the best cruiser eBike on the market! Disc brakes are a must on any eBike, the added stopping power inspires confidence. We went a step further with the Zurich model over our normal Tektro hydraulic brakes. The Zurich is a 4 piston brake, where many brakes are either a 1 or 2 piston version.
A bike in this category should be simple to operate. Effectively keep the battery charged, air in the tires and you are good to go. That is why we use a Sturmey Archer internal gear hub. This 3 speed hub is simple and strong. It features the equivalent upper and lower gear ratios of any 7 speed system, and that is enough to get you up most hills, and achieve top speeds approaching 30 mph!
One thing that everyone loves about our bikes is the ergonomics. We get tired of leaning over, with numb hands and and uncomfortable seat. First off we feature one of the best seats for cruisers on the market. This quilted saddle features multiple layers of foam, so it has just the right density. Additionally, it has two rubber elastomer shocks built in as well. All this makes for a comfortable sitting position.
From there, the dimensions of our bike try to position your shoulders directly above your hips. We help that with our BMX style rise bars. These provide just over 7″ of height, and are fairly wide as well. The Sonic features a MTB style direct mount stem and a 31.8 bar size. So it is light weight and strong. The cross bar is there for looks, but also to support the bars for added strength.
We feature CNC billet platform pedals that are color coded to the bike model. Not only do these look sharp, they also support your feet and prevent slippage.
When we completed the design of the Sonic Stomper, we wanted to make sure that we built a bike that we wanted. It had to be strong, fast, comfortable and easy to ride. Test ride one today, and you too will find how great this bike is!
