Battery Safety

E-Bike Battery Safety Reminders

We recently got a nice reminder from our E-bike kit supplier, Electric Bike Technologies. We want you to enjoy your e-bike safely and for a long time. So we thought we we'd share this with you....


We urge you to consider the following five essential guidelines when charging your Lithium-ion battery:


  1. Do Not Leave Your Battery Charger Connected Indefinitely. Disconnect the charger promptly once the battery charge is complete.
  2. Always Use the Charger Provided with Your Battery. Avoid using a charger with a different voltage.
  3. Never Attempt to Modify Your Battery or Charger. Any alterations can pose serious safety risks.
  4. Chargers May Generate Heat During the Charging Process. Always ensure your battery is not being charged near any flammable materials.
  5. Refrain From Using Extension Cords or Power Strips When Charging. Always plug your charger directly into a wall outlet.

And always plug the charger into the wall FIRST, before plugging it into the bike.

Introduction to Your PedalChopper

Introduction to Your New PedalChopper Motorized Bike

If you are new to motorized Bikes, here are a few reminders. All motors require a breaking in period. Here at PedalChopper I have test ridden your bike to make sure everything is in proper order. But you still should take it easy on the bike for approximately 2-3 tank fulls of fuel.  It is o.k. to run  it  up to full throttle but only for 45 seconds at a time  -  for say first 100 miles or so.

Don't use old fuel. I recommend you purchase a new /clean 1 or 2 gallon gas container. You must mix 2 stroke motor oil in your gasoline or you will destroy your engine. I offer a good oil here. Or 2 stroke motor oil is available auto parts store, marine supply, hardware stores or even Walmart. Follow the instructions on the bottle. Typically you will use  4 ounces of oil per gallon of gas. I recommend full synthetic 2 stroke oil. 

Don't overfill your gas tank. 3/4 of a tank is recommended as the cap on your fuel tank is vented so gas is able to splash out if you overfill.

If you have received your PedalChopper in a carton, follow the attached assembly instructions. Make sure parts are installed properly and tight.

To start your PedalChopper raise the choke lever on the carburetor all the way up. Squeeze the left brake lever style clutch all the way in and start pedaling.Once you get up to 6+ mph, release the clutch lever and continue pedaling until the unit fires up. At this point, while the engine is running, pepper the throttle as needed to keep it running.Ride at low speed/idle for a minute to give the engine time to warm up.After the first minute or two, you can readjust the choke to 1/2 way position. Within 3-5 minutes the unit should be warmed up and ready to run normally. with choke.pushed all the 100's of hours of enjoyment, if you take care of them.

Get Better Performance

All motors with aftermarket high compression head run much better with high octane fuel. Always use premium. And I always add 1 ounce per gallon of octane boost. It's inexpensive and can be found at Walmart or Auto Zone. USE 1 OUNCE PER GALLON ONLY. If you have not already installed it, my aftermarket ignition system will smooth out engine vibration. And to smooth out engine further, my carburetor solution is the ticket. See it at

Best Fuel Mixture for Motorized Bicycle

I recommend always using premium gasoline- the highest octane available at the gas pump. Then, it is best to use synthetic 2 stroke motor oil  [ non sysnthetic creates more sludge] . Dino at Screaming Roo says 50:1 mix which minimizes sludge and is really adequate for lubrication and cooling. I have seen recommendations ranging from 16:1 to 100:1. From my experience running too much oil hurts more than it helps. I have had stock exhaust pipes plug solid with from using too much oil. And I have seen engines gummed up from too heavy of a mix. Dino of Screaming Roo would be the expert. He has taken apart and put together these 2 stroke bicycle motors more times in one day than the majority of us will ever do in a lifetime. If he says 50:1 that would be the proper ratio. However, I like to play it safe also. So I typically go with 3.5 ounces of Amsoil Dominator [available at link] per  gallon of premium gasoline, which equals around 40:1 ratio. Of course most of my work is on new engines, that have not been broken in at all. So, 50:1 is the ticket. Finally the icing on the cake , I pick up 104 octane boost  [Walmart] as these engines really love octane.Note : no more than one ounce [shot glass] of 104 octane per gallon or the engine may not run if you use too much.Summary: Highest octane premium fuels/ Amsoil 2 stroke/ 104 octane boost.

Color a Stingray

Just something fun today...

My wife just published an adult coloring book. If you'd like, you can see it here: "Coloring Therapy - Relaxation", by C.K. Wilson. While the picture to the left is not her usual style, she thought you might enjoy a free coloring page of a PedalChopper Stingray. Just click this link to DOWNLOAD.It should print up as 8x 10 picture. Use markers, colored pencils, or gel pens to see what your PedalChopper could look like in different colors. Or the kids might enjoy coloring it, too.

If you care to learn any more about adult coloring books, coloring for relaxation or stress relief, etc., you are welcome to visit her page at ColoringTherapy/

How Fast Is A Motorized Bike?

The top speed of a motorized bike can vary. But let's first be clear...this is not a motorcycle. Nor would you want to be going those kinds of speeds on a regular bicycle frame. Here at PedalChoppeer, I only sell and use high quality engines. They generally give you 30-50mph. The top speed you get out of them will vary depending on what specialty parts you use.We carry a variety of high performance parts. For instance, one of our high compression heads will add 10- 12 mph to your top end. That is plenty of speed to really be a blast to ride, as well as get you where you are going in good time.

Don't forget, just because it is NOT a motorcycle, doesn't mean you don't need a helmet. Accidents can happen at any speed and this is faster than you would be riding if you just pedaled. My customers often prefer a motorcyle style half helmet like this one - . I like the look of the flat black and it's light weight. It looks cool while still being DOT approved if you are required to wear a helmet where you are riding.
