I just went to Bike Friday's site. A couple things I like and a couple I don't like. First, I think disc brakes are a must with electric bikes and this is only available on their cargo unless I didn't get the right information. Second I would definitely go with the front hub motor ... that...

I have two front hub motor bicycles and my experience has been very positive. The advantage was it is the easiest to install if you want to build yourself and it works extremely well with folding bicycles. The bikes I have are Tern folders (Verge S8i and the Eclipse) that have 8 speed and an...

Got the baserunner_Z9. It fits very nicely into the packaging of the battery. Phaserunner is a separate package that would have to find a place to mount on the frame.

Hello All, Finally found another Tern folding bike to convert. I picked up a used Tern Eclipse that has the features I like in a bike. My previous project was a Tern Verge Si8 and its been trouble free and offers numerous features that lend itself to be an excellent conversion. The Tern...

Just like to add...don't put a BBSHD 1000w motor on this bike of yours without disc brakes. Asking for trouble, it will go but just as important it has to stop!

I did this kinda of thing with a folding TERN Si8. It has a belt drive and 8 speed belt drive Alfina hub. Search this forum and you will find my postings on this subject. Lots of information there but I would recommend you go to GRIN techologies and look at their Bafang 311 front hub kit...

Here is a posting that I did last year regarding my installation of a 200 Watt panel system. These parts were all available from Amazon and I have used this setup to totally charge my Tern Si8 converted E-bike for the last year. I am not sure what you mean by portable??? Do you want this...

I hate to ask a couple of simple questions. How can they sell this legally? Isn't the speed limit suppose to be < 20 mph?

You can just use your aluminum forks but add a torque arm. It works with my bike and I totally trust it. Shipping from GRIN technologies shouldn't be that expensive. The arm itself was designed by a couple of very capable mechanical engineers and are about 1/4" thick and would handle the...

Torque arm that I bought for my Tern Verge Si8 was not that expensive. I think around $27 Can...cheaper than buying another bike. Are you not mechanically inclined? What Thomas is recommending makes perfect sense and safe.

Sounds like you have a faulty wheel bearing. Do the spokes ring tight (tap on them and listen to them and they should have a slightly "ping")? Maybe the wheel needs to be examined.

All M/C suspension front ends use oil and have complex damping mechanism built into the down tubes. I know, I just replaced the fork seals on my Suzuki M/C. There are orifices and damping oil along with a spring and I wonder if e-bikes are the same. Does the oil in the front end of a...

A question...are the front suspension on e-bikes hydraulic and springs or just springs? Are both front units suspended with a hydraulic oil inside them and what would be the maintenance. I am assuming the suspension system is just like the motorcycle suspension so there is a damping of the...

A question...are the front suspension on the HSD and GSD hydraulic and springs or just springs? Are both front units suspended with a hydraulic oil inside them and what would be the maintenance. I am assuming the suspension system is just like the motorcycle suspension so there is a damping of...

OK but actually, the firmware is just an update from my understanding and not a means to access the parameters of your controller in most cases. I am sure Bosch doesn't allow even the dealers to play around with the parameters. Cycle Analyst does allow some degree of access and even with this...

I don't know anything about your motor...you may have to research this on your own. Google is a great place to start. For instance I would just search for the "Repair shop for my electric bike in the NY area- Stromer bike" or where ever else you live.

I just charged my battery for the 4th time with the solar panel setup.....works like a charm!

Do you have a multi meter and know how to use it?

Just commenting here to place this at the top of the list....for those in California who are thinking about a solar panel setup since you are going through a power shut down.

OK Guys, For those who are thinking about building a solar charging station for their EV bikes. Here are the parts that I have used to accomplish this task. First off, I am not endorsing any particular manufacturer or brand but just listing what I use. All these items I purchased from Amazon...
