Currie Technologies has really gone all out with this new high speed (28 mph) e-mtb that features a 350 watt mid drive motor, 48V mid mount lithium battery, 27.5″ (650b) wheels, RockShox suspension fork, and more!...
The IZIP E3 Peak is priced at $3,000 USD at the time of this review.
that looks like a really nice and practical bike, and half the price of a Specialized Turbo! :-)
I always wonder about those top speed claims. They usually seem to be no load speeds, meaning the cruising speed of the bike is about 15% lower than that.
I built a bike kinda like that, with a hub motor though. Top speed (i.e. no load speed) is 29mph, cruised to work on it at 25mph today. Home built bike cost about $600 (actually cost me about $200 since I am sharing the battery from another bike).
Still, that seems like a pretty practical bike. I like the battery, and the mid drive mated to a decent mountain bike frame. They have kept the weight down low.
The one big problem: 28mph with 48v8.7Ah is going to give you a pretty limited range.
for this kind of money I would rather choose BOSH bottom bracket drive equipped ebike.
There is a reason respectable manufacturers use them.
Note that the Peak will do 28-30 (verified by my GPS). It is the real deal and is solidly built. The Bosch mtb units limit you to 20mph. The latest Bosch "performance line" drives put out 60nm of torque vs the Peak at 73nm. The transx mid-drive in the Peak has so far proven to be
trouble-free and work great if you just learn to pause briefly before shifts. Also, keep in mind that the Bosch drive mountain bikes are significantly more $. The Peak is rather unique as a high speed pedelec and a mountain bike.
