Re: battery mounting outside downtube

In a few days, after 400 miles on the bike, I'll post pics of my battery mounted on the left side of the front "triangle" area.

This works very well and gives a good center of gravity when stopped. When the rider is mounted, rider weight on the bike, even a rear rack mounted battery is OK.

Re: pedal assist way too fast!!!!

Throttle is good, it gives you the assist you desire.

PAS is mostly bad. Only torque measuring pas is OK and then only OK, not good.

Poorly implemented pas is high risk and dangerous.

Throttle is not high risk and dangerous, it works like your car, truck, suv, motorcycle, scooter, etc.

Re: bbs02 - what size chainring for my commuter?

Rpm based pas is just wrong. Torque pas is better but a BBSxx doesn't have it. Throttle is best, you add the assist that feels right. BBSxx controllers are now programmed incorrectly. Therefore, BBSxx is not a good choice.

Re: E-bike for 2 grand ?

You can easily have a good and serviceable ebike within your price limit. A used bike with steel frame and fork is a good place to start. Steel has much better metal fatigue properties than aluminum, that said aluminum can work too, especially if little used. Never drill holes in a frame or fork, ne...

Re: What E-Bike Rack do you use?

Performance Bicycle brand rack that is similar to the Swagman and the Hollywood. The tires sit in cradles, the center rod folds toward the rear to load the bike closest to the car. Rearward folding is very important, it allows both bikes to tilt rearward, tilt is stopped by the cable that locks them...

Re: Why I'm pulling my Bafang BBS02

I looked at the BBS02 and BBSHD, as well as other mid drives. Bafangs throttle problems were unacceptable, the TZ needed programming. I bought a MAC 12t rear hub motor. It took a few days to make torque arms for both sides, this included cutting steel, drilling, filing, fitting and welding, along wi...

Re: Dash cam

Around 15 years ago I saw a tadpole bike with a pusher trailer, at a bike shop. The owner used a rear facing camera similar to a GoPro, to record vehicles that buzzed him. He ro...

Re: Tried Topeak Beam seatpost rack with panniers

This seatpost rack has carried the battery on t...

Tried Topeak Beam seatpost rack with panniers

This was the type V rack, it angles down from the seatpost and then horizontally back. It carries the load lower than a straight backward rack. Side frames are available to carry panniers. Topeak makes a really nice quick disconnect bag with panniers to fit on this rack. Got this to carry my 52v, 20...

Looks like Izip made changes from year to year. Specs from the 2014 indicate a 48 V, 8.8 Ah battery Lion type. 48 V, Lion is a very standard battery. A new one could be mounted on the rack or in the triangle. 8.8 Ah is a pretty low capacity, higher capacity would be somewhat larger and heavier but m...

Re: Buying first system - Need input please.

Your bike is ideal for conversion to electric. A front or rear hub motor should work, Grin in Canada makes really nice torque arms but you can make them yourself with a drill, hacksaw and hand files, files for sharpening chainsaws work great. Mounting the battery in the front triangle gives better w...

An older Mongoose with MAC 12T and 52V, 20Ah battery.

Now building a battery box to mount the battery over the top tube, since it won't fit under the down tube.

Edit to add, 105 miles so far, no problems. Miles per Ah are around 5.55 average.
