Ultra Motors A2B
4.0 Stars - Has filed for Bankruptcy. Check before purchase.
Ultra Motors produces the A2B, a distinctively styled eBike/scooter. The rig is not your traditional bike, and that is what makes it interesting.
Specs for the bike, however, are similar to many eBikes on the market today. The A2B is driven by a 500 Watt motor powered by a 36 volt Li-ion battery pack mounted on a fixed rear rack. It is a neat package. Extra packs may be plugged in for extended range.
Top powered speed is 20 mph. Gears are a 7-speed rear cluster shifted through a Shimano derailleur. Brakes are disc, front and rear. You may not want to pedal the bike too far since it tips the scale at 72 pounds.
The A2B is one interesting eBike. We like it and know others who feel the same. However, some reviewers have had a few problems. Still, even at $2,699 US, we can recommend it.
Urban Mover has been making eBikes for some years. The current line includes 7 models. Urban Movers are pretty light weight in the world of eBikes. The models below are similar, with variations in power package (24 or 36 volts) and frame styles. All are driven by 200-250 Watt hub motors.
Urban Mover customers like their bikes, but most mention some kind of defects in the electronics or accessories. Prices on the Urban Mover line are quite reasonable, and over the build quality seems to be good.
UM26S Terrain: This is the Urban Mover Folding eBike. It is powered by a front hub motor, and rear 5-speed hub for pedaling. The bike is a very light alloy frame for an eBike at 43 pounds. The pedals also fold, and the whole rig pops into a storage bag...pretty neat. Price is $950 US.
UM33X Umotion: This is the entry level eBike. It is a MTB frame driven by a 200 - 250 Watt rear hub motor. The motor is powered by a 24 volt 9AH Li-ion pack.
