Re: Off the line torque - DD motors

Electric motors, the ones we use, produce some cogging effect at low rpm. At higher rpm it's there but not noticeable. Cogging is normal and noticeable at low rpm. It comes from magnets and poles passing each other. Comparing direct drive with gear drive: if a DD hub motor has cogging you can feel f...

Saw many fat tire ebikes this weekend

Sand Fest happened in Port Aransas, TX this past weekend. Many sand sculptures are built before the opening on Friday, the event continues through Sunday. We went on Friday and Saturday, Friday has more locals and fewer tourists. We saw a lot of fat tire ebikes on Friday, most looked like factory bu...

Re: Hybrid road bike ebike conversion

Extremely do-able, it should work very well. Last year I rode around 1200 miles using a front hub motor and another 900 miles using a rear hub motor. I can't tell the difference between them when riding on dry pavement. Steep climbing on dirt is different, the rear hub motor worked better. Well, a f...

Re: Advice for starting out a new conversion (UK)

20 miles each way, 40 miles total on one charge is easy to do with a big enough battery. I'm using a 20ah, 14s, 8p, 18650 cell battery, with your fitness, weight and bikes, you could easily do 30 miles each way. It's an inexpensive battery from Amazon and has never been a problem. It looks like many...

The battery for the Speedway IV Pro is 14s, 8p of 18650 cells, same as my ebike, it should work really well and have excellent range. A long time ago I rode a small escoot...

Re: With a MAC10T, what provides is the pedelec functionality?

Re: Dual Motor, 20x4" Fat Tires, Suspension

I'd sure like to ride one of those bikes.

Saw two ebikes on the street today, both appeared to be 20" or 24" fat tire bikes that had throttles along with pedaling. Both riders had big smiles as they started uphill.

Re: Full suspension bikes compatible with a frame battery

Re: Dual Motor, 20x4" Fat Tires, Suspension

Most of the ebikes I see lately have similar tires and layout but without rear or even any suspension.

That should be a very competent bike. A throttle would be a huge plus.

Re: eZip Trailz Commuter Low Step

30 degrees is 58 percent grade. Stairs have around a 65 percent grade. If that's the case, the bike needs a geared hub motor and a Cycle Analyst V3, set the cruise control when walking next to the bike and let the bike power itself and help you walk next to it, at about 0.5 mph. The steepest streets...

Re: How many watts do I need?

There are watts calculated from climb speed and weight. There are watts needed to maintain that speed due to rolling friction and air drag. Then there are watts needed to overcome inefficiencies in the drive train, tires, wheel hubs, etc. Total watts include the preceding power requirements. Human w...

Re: Geared Hub vs Mid-Drive?

9% is a significant grade, but it's at the end of the ride so you'll be warmed up. Road speed during the climb is a big deal, slower uses less total watts. Motor watts = total watts minus human watts. The lower the climb speed, the lower the motors share of total power output. There is a tendency to...

Panniers vs top of the rack bag and backpack.

For decades I used a top of the rear rack bag and sometimes a backpack. When the ebike came along I put the battery in the rack-top bag. Because of ageing it became harder to get a leg over the rear bag. Also balance when stopped on a climb was a problem, the bike tended to rotate nose upward about ...

All-Axle is a front hub, GMAC a rear. When riding pavement I can't tell the which I'm using, until there are bumps. Off road front hubs break front wheel traction more often than rear hubs break rear wheel traction. Front hubs transmit shock up through the front forks to the handlebars, too much for...
