    Not really advanced but - cassette wear after first 180 miles?

    I like the BaFang mid-drive motors because they have a shift sensor available that cuts off the motor for a second or two when shifting. Impossible to power shift. All mid drive motors will put more wear on the chain and gears because all the torque of the motor is directly applied to the...

    Axle-mount bike trailers w/ GMAC?

    I have the 8TGMAC motor in my RV-2 velomobile. The velo came with QR 406mm rims. I had no problem mounting a axel mounted hitch for a Wike flatbed cargo trailer on the axel. However with the 406mm (20 inch wheels) The trailer was very much nose down definitely not anywhere near level...

    Chain Wear

    I do believe that mid drives will cause more wear because the torque of the motor goes directly to the chain and gears. You can get less wear by always starting up using the pedals and power level 1. Avoid power levels 4 & 5. Use the gears just like you would on a regular bike. I have a...

    Chicago Lakefront Trail?

    I do not remember the Lake front trail having a speed limit. But I do remember that Class 3 e-bikes are prohibited. So in a sense there is a speed limit of sorts.

    Inner tubes. Our friend AND enemy.

    Try it, You'll like it! The first wheel I tried mounting the 55-406 Schwalbe Pickup tire onto had a 19mm inner diameter width which is about the narrowest rim that will take a 55-406 tire and using a Heavy duty tube made it especially difficult to mount. It took me over a half hour and 10 zip...

    Inner tubes. Our friend AND enemy.

    There is a product or rather a device called a Tyre Glider. I can tell you that it really makes getting the wire bead back on the rim a breeze. Even using it to take the tire off us easier than using levers. I confess that I do use a lever to help get the glider under the bead. A few months...

    Flat tires

    Those fine thin piece of wire flats can be the most frustrating kind to find the wire. I use the Schwalbe pickup tires on the rear wheel (hub motor) on my recumbent e-trikes and e-velomobile for more than 5 years and no wire flats yet. But I do use Mr Tuffy tire liners and thorn resistant...

    Inner tubes. Our friend AND enemy.

    About a year ago or so I bought a pair of "jack stands" for bicycles that clamp onto the handlebars. They are foldable and light weight and let you to be able to flip and stand a bike upside down without having to worry about breaking off accessories or controllers. They are lightweight and do...

    Inner tubes. Our friend AND enemy.

    I have been using Sunlite HD thorn resistant tubes in my recumbent tadpole e-trikes sizes 20x2.0-2.25 and 20-2.30-2.40 for 5 years with no problems with only 1 flat that was caused by a roofing nail that got deflected by the tire liner and wore a hole in the side wall of the tube just past the...

    Tire Liners

    I have been using Mr. Tuffy tire liners since June of 2020 in any of the tires that are are around 1.95 to 2.35 inches wide on 20 inch (406mm rims). Where I live in the Chicago area goat head thorns are not a problem. But I also use heavy duty thorn resistant tubes as well in those wheels...

    Got a flat tire?

    The CA3 controller display for the 8TGMAC motor in my E-velomobile has a odometer like function that keeps tract of the total kilowatt hours of battery power that the motor has used. After 4,450 miles I have used just over 80.6 Kw/hrs. total. The cost about $11.75. Pretty cheap, I think.

    Longest lasting tire recommendation

    I switched to using Schwalbe Pickup tires in 55 & 60-406 sizes (115 & 125kg load rating at 65psi) on my tadpole type e-trike and e-velomobile. The larger air volume at a lot lower air pressure solved the problem of breaking spokes on the single rear hub motored wheel. I also use heavy duty...

    Rad Trike vs Liberty Trike

    Liberty Trikes have a new model out now with larger tires (20 inch). It is supposes to be able to go 14-16mph. It a couple pounds heavier and a few inches wider. They also changed the gearing with more teeth on the front chain ring so you can actually put leg power to the pedals above power...

    Looking for reliable 1000w rear hub motor for regen purposes

    The 8TGMAC motor has proven to really be the perfect choice for the RV-2 velomobile. The 1.2kw of REGEN braking it can provide is very effective at bring it to almost a complete stop while on a down hill coast at 60mph. without even using the 2 disc brakes on the front 2 wheels. (and a 120 load...

    Looking for reliable 1000w rear hub motor for regen purposes

    I can you about the srounging around and trying to go the "cheap" route. Sometimes it gets turned around and ends up biting you in the ass. I bought a 11 year old Sun EZ3 HD delta type semi-recumbent trike on a consignment sale from a LBS. I e-mailed Sun to find out the date it was made. It...

    Looking for reliable 1000w rear hub motor for regen purposes

    I am using a 8T winding GMAC geared rear hub motor with a 52v24ah and a 52v28.8ah battery that I installed in a TriSled RV-2 velomobile. It had been programed with with the electronic virtual freewheeling. The effect of the REGEN braking is amazing. Even when coasting down hill at 55+mph. it...

    Liberty Trike interests us for its RV-transportable. Any thoughts?

    I bought a Liberty Trike for my wife a year ago. No problems, but the back half is a little heavier than 25 lbs unless you take out the battery first. Which is not hard. The little 8amp hr battery comes up a little short in range. So I bought a 36v15ah battery on Amazon ($274.00) It is 4"...

    Is anyone trying to solve charging on the road?

    I tried using a Renology 175 watt flexable panel on a light weight aluminum frame that was strapped onto the top of the cargo bin in the flat bed (Wike) cargo trailer that I pulled with a 500watt geared hub motor on a Sun T3CX trike.. The most power it developed was 1.4 amp hours per hour, on...

    Is anyone trying to solve charging on the road?

    I have the Grin 8T GMAC installed on the rear rear wheel of a TriSled RV-2 velomobile. It shipped from Melbourne, Austrailia 15 Feb. 2023 and arrived in Chicago, USA May 15. I am mentioning the shipping time because Grin was also having shipping delays getting their products from the Far East...
