I have one Kope by Dost made in Canada
RST Gila fork can get if needed still
Dual battery version
the 120 mile claim i doubt dual battery
total of 24 ah is unlikely 120 range or even 70 miles
Have 1194 miles on it. Plenty of life to go. 
 
Dost went out of business
Battery can not get
California company can rebuild the battery with orginal battery case. Never installed second battery as of still today.
 
Bike can go 30 miles per hour
battery do not like poor range. Maybe needs rebuilt for better range. Review has it a better range than real life. Maybe needs battery rebuild. California battery company $500, also they test first battery cells. Not bad deal it seems get all new cells and tested.
 
The bike has 9 PAS levels
 
Does ride nice. Only issue is range. Nice ebike. 
Below review i found.
 
KOPECHAIN
UP TO 70 MILES 
UP TO 120 MILES RANGE
750W MID-DRIVE + THROTTLE
48V 14 AH + 48V 10.4AH*
DŌST Kope was used to break the world record for the longest journey ever made on an motorized bicycle.
The KOPE has a traditional drivetrain that uses the SRAM X5 derailleur to change gears and KMC roller chain to transmit power to the rear wheel. 
The light-weight, ultimate efficiency, and the ability to repair in case of a roadside emergency make this design popular with sport-minded riders and traditionalists familiar with the components that make up their bike.

The KMC chain is highly corrosion-resistant (even in winter riding conditions), though all chains require regular maintenance depending on the use and riding conditions.
SHIFTER & DERAILLEUR
Thumb shifters enable precise gear changes of the derailleur. A traditional 9-speed derailleur with an 11/34 tooth cassette provides a wide range for hill-climbing and high speeds. 
Each DŌST is equipped with a high-performance 750W mid-drive motor to elevate the throttle and pedal assist with both satisfying high speeds and hill-climbing (120nM of torque) capabilities.

Dual Battery System
Eliminate range anxiety with the DŌST Optional Dual Battery System providing an overwhelming 180 km (120 mi) of range via the 25 Ah (1200 Wh) combined battery capacity.

Upright Riding Position
Our Ergotech 60º angle adjustable stem can be finely tuned to your riding position to achieve a personally tailored and unique comfort.

Suspension fork
The comfortable absorbing fork comes with a sealed cartridge designed to require minimal service. This fork also features an accessible lockout to stiffen up the suspension and speed up your bike for when the riding is easy.
Integrated rear rack
The DŌST multi-purpose rear rack not only fits standard bicycle accessories like DŌST panniers & trunk bags, kid’s seats, trailers and more, but also reduces frame flex and includes an impressive 100lb payload capacity.

Integrated Lights
See and be seen with an always-on integrated LED Lezyne German StVZO 210 lumens optimized lens with both flood and long-range beams in the front with a wide light spread in the rear.

Puncture Resistant Tires
Meet the Schwalbe Super Moto X. Designed for both road and trail, this beefy and versatile tire provides comfort and grip while also including Kevlar reinforcement for fewer flats and a reflective sidewall for safety.
Summary
A sturdy, highly-functional, high-step hybrid electric bike with upgraded components and optional second battery pack. Adjustable angle stem improves fit, 100mm spring suspension fork offers compression lockout and preload, high quality 2.4" wide Schwalbe Super Moto-X tires offer stability, visible reflective sidewalls, and puncture protection lining built-in. Lots of great accessory options including bags, cup holders, suspension seat post, mirrors, and child seat
Powerful 750 watt Bafang BBS02 mid-drive motor blends into the purpose-built frame, alloy housing keeps it protected while reducing noise. With up to 120 newton meters of torque, it's a very capable climber! A physical shift-sensor cuts motor power to protect the 9-speed Shimano Altus 11-36 tooth drivetrain whether you're in pedal assist or throttle mode
 
Main battery pack is removable, optional second pack can be added and installed anytime in the future. USB charging port built into the color LCD display panel for smartphones and other accessories. Tool-free adjustable kickstand is a nice touch. The high-step KOPE model isn't as approachable as the step-thru DROP, but is larger and stiffer . Motor uses cadence sensing vs. fancier combined cadence+torque. Fairly heavy build at ~65lbs before additional battery or accessories
