I have ordered the parts for a good small waterproof speaker and an small MP3 player. I have 12V on our DIY bikes, it is easier to wire in. Low base sounds carry farther than like High tones, But we'll get some sound out there. I will report back when I get it working

I don't know if you noticed the Boost button on my YZ250F at Glen Helen, the most recent one, but it is the Sport mode or Mode 3 put onto an easy to hit on and off on the left side. I was able to hit when needed. Bob and I were neck and neck all around the REM track, I came out a turn with...

Yes it is pretty loud. It always get a head turn.

My answer is a regular Bicycle bell. on the left bar. They are not made real solidly anymore, they kind of fall apart after some riding. I'm thinking of a motorcycle panic rev sound machine, my next invention.

Motoenergy has been using that method for some time. Mark is making many improvements to it in his builds internally in the motor. Just search Axial Flux on YouTube and see all who are developing that tech. Mercedes is working with Yasa a British company for a new version of this technology.

Mark at XEMX1.com has been developing the product he has today, for quite a while. It is a motor/gear reduction and Controller, with a quick change battery, all designed for the Newer YZ 250-450F chassis. This is there new web site. The battery might be able to fit in the newer 2022-2023...

My 2014 YZ250F is the one I am now riding. I love it. It weighs about 230lbs. I just put a slightly larger battery in it, and it is a blast. Here is a YouTube of it at Glen Helen. You can see some of my other builds on my YouTube channel. Here is the Motocross Action on my the build I...

No I haven't. But I have ridden an Alta, and the 268lbs is a killer for me. I am 78 years old, I was a young 76 when I ordered it. But it is really tough to pick that much weight up. I know, don't fall down... The conversions we are building have enough power for my riding and good newer...

Thanks for the info. I will delete my email , this is just a general info email. But I do want to sell it, if any one is interested.

Probably. These friends and I were October 31 and now Jan15 2024

How long did it take to bring the battery back to full charge with your 2 charger system. And how big is your generator?

Your conversion looks really good. The battery is such a difficult part of every build. Also since every build seems to be in a different frame. Im looking at the battery you used, as a solution, they build a great battery. Fusible links, the right cells and quantity, they disable discharge BMS...

I usually mount the motor with 3 points, the swing arm bolt, and the 2 sets of mounts at the bottom of the motor. So I just ran the mount to the front since the middle bottom bolts only go to the plate. These little motors put out some really awesome torque. I would rather be on the side of...

https://www.instagram.com/reel/CxI6ZkppduN/?igshid=MzRlODBiNWFlZA== 3 monthes ago I was riding at Cahuilla Creek Mx track on Bob Casper's Honda Ebike 2010 250 CRF with the same motor /Controller on it. I came in and Bob was talking to Brock. Brock wanted his son to try this ebike and Bob was...

I have 2 frames KX85 2003, partial roller and a roller. Both frames have been modified to accept the QS138 70H V3 motor and the EM150 controller. 1.)The one has frame, rear suspension and shock and rear wheel. $400 + shipping no title IMG4277,4278,4279 2.)The other has small wheel front...

Just the outer shell and do these few mods to it. A little plastic welding...

Here is a sound test and load test of this generator. Costco had this generator last year, and sold them all. now they have them back. That is a good price. . Sound is actually good on this, pretty comparable to all quiet type generators. It only reaches 71db at close to full load. the...

No I haven't seen any aftermarket battery system. Unfortunately the easiest way would to replace the battery and controller. But there are very few 350V controllers. I could reload an Alta battery, but not real sure if I could get the wire bond type connection with solder and wire. There are...

I have 2 x 10A 120V chargers, since I have split my battery into 2 packs, and charge them both at the same time. 120V is available some tracks, but I have a 3500W inverter generator that can run 2 15A chargers. That brings the battery back to 80-90% in 45 minutes from about 50%. 15A charger is...

So I turned 78 last month. All is well. The YZ250F 2014 Electric is about 6 months old and it has 300-400 moto laps on it, ridden most by a older rider, but it has been near flawless. The battery packs have given me a few problems, but this is their second career on this bike. They have...
