Re: Tell me about MAC 3 speed and cruise button

"Well ... all I know is the title "3 Speed Switch With Cruise Function", on their site under (for example) https://em3ev.com/shop/mac-kit-47v-batt ... 1200w-max/. It probably is two things: 1. A choice of 3 throttle ranges, with different top end speeds. 2. A cruise control, which will lock in the c...

Re: Converting a beach cruiser with front wheel motor.

Love that U brake with the built in housing stop. That really makes sense and makes things easier. My host bike is about 45 years old, just moved the ebike stuff over to a modern bike, only a 17 year old design. Had not a clue about a U brake with built in housing. Thanks for posting that pic and le...

Re: Wooden sticks

In 1967 I had to change the clutch on a Pontiac Firebird that was a few months old. To remove the transmission a cross member had to be removed. Cross members were bolted in unless GM ran out of bolts, in that case they were riveted in, if GM ran out of rivets too, the cross members were welded in. ...

Re: Converting a beach cruiser with front wheel motor.

Brakes like the Odyssey Springfield or Diatech Hombre require some sort of cable housing stop, for the end of the brake cable housing. Typically, the cable stop would be mounted on the stem, the end of the brake cable housing rests in the housing stop, the cable extends down to a yoke that pulls up ...

Re: Converting a beach cruiser with front wheel motor.

I've been riding a direct drive front hub motor, 26" conversion bike since 2014. 410 miles last month and 31.6 miles today. Front hub motors work, both direct drive and gear hubs work well. Mine runs fine on 48 volts and 36 volts, there is little difference in performance but I never use a lot of th...

Tell me about MAC 3 speed and cruise button

I'm looking for a rear hub motor, 135 mm spacing, that can give a gentle start and some power for walking beside me on very difficult climbs. Also, sometimes I do some very slow riding, often with a foot or two paddling, following the grandson. Then there is starting on a steep uphill, some good, co...

Re: Bafang G311 front hub speed limit

The G311 and G310 hub motors both use a smaller motor and more gear reduction than most gear hub motors. This makes them smaller and lighter than most geared hub motors. Gear reduction is something like 11:1, compared to 5:1 in most hub motors. So, the motor in a G311/G310 spins more than twice the ...

Re: Building my first bike - A few questions

An older bike with steel frame would be a good host bike, especially with respect to rear dropout strength to resist hub motor axle torque and dropout twist out. Be sure and use a torque arm, Grin in Canada makes good torque arms. I'd go with a popular, high quality, brand. Used great quality is bet...

Re: M600 vs Yamaha/Brose/Bosch

I rode a Bafang mid drive today, not a BBS02 or BBSHD, but the one that is built into the frame. I've not been impressed with the BBSxx mid drives, pedal cadence PAS seems un-natural to me and the throttle response was not to my liking. This Bafang mid uses torque sensing and also has a throttle. I ...

Re: Cheapest high torque fast bike?

Aero bars are for fast, even fast climbing. Torque Sensor pedal assist is great for aero bars. Throttle has to be out on the front of the aero bars. Also, aero bars carry a lot of your weight on the arm cups, that reduces saddle weight and saddle pain. Non sense speed limiting is a bad thing. Life o...

Re: DIY Onyx style build advice

As an example of a heavier direct drive, my front hub wheel weighs 25 pounds, this is on a 26" wheel, with tire and tube installed. Battery is 48v, 13s, 4p. The motor winding in this hub delivers about 25 mph top speed, about 40 kph. This DD hub motor would be inadequate for your use. My total weigh...

Re: One Wheel not a bike but beauty in motion

Dangerous indeed, high risk, but the reward is very high for a really good rider. One Wheel is not for everybody. Motor stopping on a Segway would also put the rider in a bad situation, but they are very reliable. After an hour on a Segway I got off and walked into a restroom, walking felt very disa...

Re: Ebike kit advice.

My torque arms from Grin in Canada are far better than the torque arm looking objects from Luna.

Edit to add: the Grin arms are thicker and more carefully and precisely made. They are just better.

My Luna battery is 3.5 years old and working very well.

Re: Looking for input on my first Ebike build and questions about battery range/usage

Forgot some numbers, this is for 282 miles of careful record keeping. Average miles per 1 volt drop, dV, is 3.57 miles per volt. This is voltage for the "48" volt pack. Starting voltage is 52.1 volts, lowest comfortable voltage is 45.5 volts. Maximum comfortable voltage drop would be 52.1v - 45.5v =...

630 miles on a Jamis Hudson Sport host bike

The Hudson is a semi flat foot, semi pedal forward bike. It's probably between a normal bike and a Townie. The Townie is probably more pedal forward. It is easy to stand when needed while riding the Hudson. Getting weight over the pedals is not difficult but getting enough toe touch when stopped is ...
